[name_m]Hi[/name_m] there.
Here are my thoughts on your lists:
Boy-
[name_m]Cove[/name_m]-This is terrible, but is it too close to Covid? I used to (like a month ago) think that this was a beautiful name. Now I’m worried in what the world is going to that it’d be too close for comfort.
[name_u]River[/name_u]-I adore this name. It’s rugged yet soft & nature-y. It’s really cool w/[name_m]Jax[/name_m] too. It’s unique yet simple & well know.
[name_u]August[/name_u]-Another very handsome choice. It’s strong & old fashioned, yet sounds fresh. [name_m]Jackson[/name_m] & [name_u]August[/name_u] are great together. I love the nns [name_m]Augie[/name_m] & [name_u]Gus[/name_u] too.
[name_m]Greyson[/name_m]-This name doesn’t excite me as much. It has the same ‘son’ ending as [name_m]Jackson[/name_m], so seems a bit match-y. And is just really popular & trendy. Kind of lacks substance.
[name_u]Chase[/name_u]-[name_u]Chase[/name_u] is cool. Reminds me of a baseball player name. It’s really cute w/[name_m]Jax[/name_m] too, but seems like it should have a full name. [name_m]Charles[/name_m] nn [name_u]Chase[/name_u]? You could do [name_m]Chester[/name_m] too, but meh…
[name_m]Beckett[/name_m]-This is fun. Sort of cowboy-y like [name_m]Jackson[/name_m]. I love the nn [name_u]Kit[/name_u]! Not too common, but well known & simple.
[name_m]Luka[/name_m]/[name_u]Luca[/name_u]-I love this one. [name_u]Luca[/name_u] looks more natural to me. It’s honestly my favorite from your list, but it’s not my favorite w/[name_m]Jax[/name_m]. Not sure how much that matters to you.
Boy suggestions-
[name_m]Austin[/name_m]
[name_m]Asher[/name_m]
[name_u]Brennan[/name_u]
[name_m]Chance[/name_m] or [name_m]Charles[/name_m] nn [name_m]Chance[/name_m]
[name_u]Casey[/name_u]
[name_m]Conor[/name_m]
[name_m]Clayton[/name_m]/[name_m]Clay[/name_m]
[name_m]Holden[/name_m]
[name_u]Kai[/name_u]
[name_m]Luke[/name_m]-I honestly prefer [name_u]Luca[/name_u] in general, but [name_m]Jackson[/name_m] & [name_m]Luke[/name_m] are darling together.
[name_u]Owen[/name_u]
[name_u]Rafe[/name_u]
[name_u]Rowan[/name_u]
[name_m]Rider[/name_m]
[name_u]Sawyer[/name_u]

[name_m]Wyatt[/name_m]
Girl-
[name_u]Harper[/name_u]-This goes well w/[name_m]Jackson[/name_m]. It’s not my personal favorite. It’s just awfully trendy, but it’s not horrible.
[name_f]Indie[/name_f]-This has a pretty sound, but seems sort of not like a real name to me. I do love [name_u]Indigo[/name_u] though! What do you think of [name_u]Indigo[/name_u] nn [name_f]Indie[/name_f]? That seems more complete, & has beautiful imagery.
[name_f]Carsyn[/name_f]-Meh. This is too close to [name_m]JackSON[/name_m], & also just too masculine in my opinion.
[name_f]Harlow[/name_f]-This is more unique, but I prefer [name_u]Harper[/name_u] of the ‘Har’ names. This always reminds me of harlot.
[name_f]Leila[/name_f]-This is pretty. Is the pronunciation tricky, or is that just me? I never know if this is [name_m]Lay[/name_m]-luh or [name_u]Lee[/name_u]-luh. I like both, & I’m thinking you mean ‘[name_m]Lay[/name_m]-luh’.
[name_f]Scotland[/name_f]-I don’t care for this one. It seems a bit not like a name & kind of masculine.
[name_f]Hazel[/name_f]-This is a good vintage name. I like it for you. It’s awfully common if that bothers you, but pretty.
