I’m kind of the opposite. I can see a [name_f]Beatrix[/name_f] in high school more than a [name_f]Beatrice[/name_f]. Still sometimes when I picture a [name_f]Beatrice[/name_f] I picture an old lady like in the Esurance commercials, though when I see a [name_f]Beatrix[/name_f] I see the main character in the Kill [name_m]Bill[/name_m] movies (who is named [name_f]Beatrix[/name_f]) and I also see [name_f]Beatrix[/name_f] [name_m]Potter[/name_m].
It sounds to me like you’re over-thinking this. [name_f]Beatrix[/name_f] or [name_f]Beatrice[/name_f], and call her [name_f]Bea[/name_f]. People will hear that and not call her [name_f]Trixie[/name_f].

I like [name_f]Beatrix[/name_f] and [name_f]Beatriz[/name_f] for the reasons you stated. I don’t think [name_f]Beatrice[/name_f] is really too dated, but the x or z versions sound a bit more dynamic.
My thoughts exactly! Though I’m warming a bit more to [name_f]Beatrix[/name_f] because it’s more familiar and I love the X sound with it.

I like both Beatriz and Beatrice but don’t really care for Beatrix. I’m used to Beatriz because it’s the spelling used in Portugal (my mom is Portuguese and I actually have a cousin named Beatriz). Even though it’s old fashioned, it’s a top 10 name there right now so I don’t picture an old lady when I hear any version of it (either Beatriz/Beatrice/Beatrix), but rather a little kid. I prefer the nn Bea aswell. If you choose Beatrix though, I don’t think anyone would call her Trix/Trixie, as long as you call her Bea. Just make it clear that Bea is her nn and I’m pretty sure that will stick.
I like all combos of the name. Working with children I have come across several [name_f]Beatrice[/name_f]'s and think the name has a lovely vintage charm, I don’t see it as outdated in the slightest, the girls went in the nn of [name_f]Bea[/name_f] and one was called bumble 
I only know of one [name_f]Beatrix[/name_f] and I think this gives a classic name a more vibrant and dated twist, making the name feel fresher. For [name_f]Beatriz[/name_f] if you are going to stick with the pronunciation of [name_f]Beatrice[/name_f] I wouldn’t bother with the ‘z’ as I think people will try saying it with a ‘z’ at the end and this will only lead to frustration.
I like [name_f]Beatrice[/name_f] and [name_f]Beatrix[/name_f] and I think most people will call her [name_f]Bea[/name_f] if you have done so from an early age. The nn [name_f]Trixie[/name_f] may come when she is older by her friends.
[name_f]Beatrice[/name_f]. I don’t like [name_f]Beatrix[/name_f] or [name_f]Beatriz[/name_f] at all sorry.
I would select either [name_f]Beatrix[/name_f] or [name_f]Beatrice[/name_f]. I love the connections to [name_f]Beatrix[/name_f] [name_m]Potter[/name_m], and the sound. [name_f]Beatrice[/name_f] is more “traditional” and I don’t think it’s an old lady name. It seems to be getting more popular.
Thanks for clearing that up! I also like Kill [name_m]Bill[/name_m], and I think [name_f]Bea[/name_f] is a totally feasible option for [name_f]Beatrix[/name_f]. [name_f]Beebee[/name_f] is also cute!
I see what you mean about [name_f]Beatriz[/name_f]. For some reason, I didn’t think about the pronunciation issue there…I think [name_f]Beatrix[/name_f] still wins my vote, but on that note I can get behind [name_f]Beatriz[/name_f]. 
[name_f]Beatrice[/name_f] is my favorite.
I find [name_f]Beatrix[/name_f] really harsh.
[name_f]Beatriz[/name_f] is fine if you’re Hispanic.
First of all, I would axe [name_f]Beatriz[/name_f] if you don’t plan on pronouncing it the Spanish way (which is bay-ah-treez, technically, I think?). It would just be confusing to everyone, a very frustrating to you and your future daughter.
I like [name_f]Beatrix[/name_f] the best. I’ve never found [name_f]Beatrice[/name_f] to be super old-fashioned, but I have found it really wishy-washy in feeling, and I really don’t find it that appealing at all (wonderful [name_m]Shakespeare[/name_m] association aside!). I adore [name_f]Beatrix[/name_f], though. It’s modern, strong feel, the zippy “X” at the end (which is so unusual for a girls’ name! There’s [name_m]Felix[/name_m] and [name_u]Lennox[/name_u], etc. for guys, but what other girls’ name ends with an “X”?). I wouldn’t be too concerned by [name_f]Trix/name_f–I wouldn’t expect it to be a problem, especially if you’re already calling her [name_f]Bea[/name_f]. [name_f]Trixie[/name_f] seems really childish to me, anyway, so I would expect she’d grow out of it by the time she might decide she might not want to be [name_f]Bea[/name_f]. I have kept [name_f]Beatrix[/name_f] off my list as a FN, but it’s mainly because I don’t like any of her nns enough to use them–not [name_f]Bea[/name_f], not [name_f]Trixie[/name_f], not [name_f]Betsy[/name_f], not [name_f]Betty[/name_f], not even the so-obscure-it-may-just-be-insane [name_f]Tess[/name_f] (well, technically, I [name_f]ADORE[/name_f] [name_f]Tess[/name_f]. I just think it’s too much to pull [name_f]Tess[/name_f] out of [name_f]Beatrix[/name_f]!).
Good luck!
[name_f]Beatriz[/name_f] is lovely, and the fact that it reflects your SO’s heritage is a major point in its favor. But I would only choose it if you plan to use the Spanish pronunciation of [name_u]Bay[/name_u]-ah-treece, at least in your family–even if others are likely to say “[name_f]Bee[/name_f]-uh-triss” from time to time. I think [name_f]Bea[/name_f] (pronounced either as [name_u]Bay[/name_u]-uh or [name_f]Bee[/name_f]) would be a cute nickname for a little [name_f]Beatriz[/name_f].
I really like the vintage vibe of [name_f]Beatrice[/name_f]. This is for sure the version I would choose. It’s one of the “old lady” names that I think is totally making a comeback and I imagine it won’t have any negative association for a little [name_f]Beatrice[/name_f] growing up in the near-future.
[name_f]Beatrix[/name_f] does feel more modern and spunky, and the [name_f]Beatrix[/name_f] [name_m]Potter[/name_m] connection is great, but I’ve heard this pronounced as [name_f]Bee[/name_f]-trix many times, and that to me is a lot less charming than [name_f]Bee[/name_f]-uh-trix (or [name_f]Bee[/name_f]-ah-triss). That, and the fact that I also don’t care for the [name_f]Trixie[/name_f] nickname is why I’d go for [name_f]Beatrice[/name_f] myself. But I do see a lot of charm in [name_f]Beatrix[/name_f].
I think [name_f]Beatriz[/name_f] is great if your SO is Hispanic. I would pronounce it the Spanish way. My fiance is Mexican and we named our daughter [name_f]Noemi[/name_f], the Spanish version of [name_f]Naomi[/name_f].
A lot of the prettier “old-fashioned” names are making a comeback, and are now considered to be elegant, sophisticated choices: [name_f]Alice[/name_f], [name_f]Clara[/name_f], [name_f]Eulalie[/name_f], [name_f]Theodora[/name_f], etc. [name_f]Beatrice[/name_f] is not even that “out there” and is, in my opinion, rather pretty. The nickname [name_f]Bea[/name_f] also brightens it up a little if need be. Old-fashioned names are only dated if they’re ugly - [name_f]Bertha[/name_f], [name_f]Edna[/name_f], [name_f]Gertrude[/name_f], [name_f]Gladys[/name_f].
[name_f]Beatrix[/name_f] is okay, though I personally prefer [name_f]Beatrice[/name_f] (to me it sounds and looks prettier). It might be an issue if you really dislike [name_f]Trix[/name_f]/[name_f]Trixie[/name_f] - people might be inclined to call her that, and she might even want to be called that.
[name_f]Beatriz[/name_f]. It would be one thing to pronounce it [name_f]Bee[/name_f]-UH-treez, which I find less pretty than [name_f]Beatrice[/name_f], but still, it’s a legitimate name. But since you say you’ll pronounce it like [name_f]Beatrice[/name_f], it just makes it seem like you’re trying to invent a new name, or are really trying to be different. It will also cause a lot of spelling/pronunciation confusion.
I think [name_f]Beatrice[/name_f] is your best choice.
Frankly? I would avoid [name_f]Beatriz[/name_f] if you aren’t a Spanish (or Portuguese) speaker; it’s either [beh-ah-TREETH] or [bee-uh-TREESH], and neither pronunciation works well in English, [name_f]IMO[/name_f].
Personally I prefer [name_f]Beatrice[/name_f], for the reasons you mention. It’s the most classic, accepted form of the name in English and it has lots of interesting namesakes ([name_m]Dante[/name_m]'s [name_f]Beatrice[/name_f]). [name_f]Beatrix[/name_f] is nice too, but I think of the Dutch [name_f]Queen[/name_f] first; I would avoid this if you don’t like [name_f]Trix[/name_f]/[name_f]Trixie[/name_f].
You’ve captured your thoughts here exceptionally well, @kisa.
I admire all three names, as well.
To me:
[name_f]Beatrice[/name_f] is more sensible/studious.
[name_f]Beatrix[/name_f] is more upbeat/playful.
[name_f]Beatriz[/name_f] is more sultry/romantic.
I’m starting to like [name_f]Beatrix[/name_f] a lot more guys. I started to get over my [name_f]Trixie[/name_f] fear, I feel that if I start off the [name_f]Bea[/name_f] nickname others will likely follow suit and if [name_f]Trixie[/name_f] starts… then I hope it’s just an endearing nickname that only people closest to her will use. I also just love the zippy X sound at the end, and it’s just more modern friendly than [name_f]Beatrice[/name_f].
I have never thought of the Dutch [name_f]Queen[/name_f] [name_f]Beatrix[/name_f] with this, but I quite like that association because I love [name_u]Holland[/name_u]. I don’t know anything about this [name_f]Queen[/name_f], so I don’t know if this is a good association to her or not.
I think I may change [name_f]Beatriz[/name_f] on my list to [name_f]Beatrix[/name_f], but keep [name_f]Beatriz[/name_f] on the back-burner encase I can get something figured out on the pronunciation front.
Though do keep the opinions coming. I love reading anything you got!
Saw this comment after I left my last comment. [name_m]Just[/name_m] had to reply saying that I love your description of all 3 of these names.
I’m a [name_f]Beatriz[/name_f] and am a native Portuguese speaker and Brazilian. In all my years living in the US, everyone always called me [name_f]Beatrice[/name_f] (the pronounciation) and none of my teacher’s ever misspelled my name. I love it because the letter “Z” adds a certain charm to it and at least to me, makes it a tiny bit more unique.
[name_f]Beatrice[/name_f] is the only other variation I love and sometimes even I like to use it. My Italian professor calls me by the Italian pronunciation (Beh-uh-tree-tche).
I simply detest [name_f]Beatrix[/name_f] and [name_f]Trixie[/name_f] especially! I see no appeal to it and personally “tricks” and “tricksters” are not cute things to call your kids. Serious negative connotations… although many on this site love it.
Oh, and my nickname has always been [name_f]Bea[/name_f] ([name_f]Bee[/name_f]-uh)! Sometimes my brother calls me [name_f]Bibi[/name_f].
I think [name_f]Beatriz[/name_f] is stunning and love that it would honor your SO’s heritage. I definitely would choose it over [name_f]Beatrix[/name_f] and [name_f]Beatrice[/name_f].
