Thanks everyone! It was a really close call for me, haha.
In the end, I decided that, I could easily and 100% see myself with a little [name_f]Maude[/name_f], but I couldnt with [name_f]Maisie[/name_f] OR [name_f]Polly[/name_f], so I went a different route 
I also ended up removing [name_f]Sophie[/name_f], [name_f]Arabella[/name_f] &[name_f]Isabelle[/name_f] from my list, although i love them (especially [name_f]Sophie[/name_f]), the popularity is a bit offputting.
Where i currently live, it seems like 8-9 years ago, everyone who was having a daughter chose some form of [name_f]Isabelle[/name_f]. Its ubiquitous now, you cant go far without hearing it.
As for [name_f]Sophie[/name_f], I know 3 little ones here, and, I am planning on one day moving to the UK (just a matter of saving). I know its off in dreamland right now, but, [name_f]Sophie[/name_f] hasnt left the UK top 10 in 20 (or more) years.
Its a bit offputting when my other choices are all decreasing in birth numbers or are new to either [name_f]England[/name_f]/[name_m]Wales[/name_m] or the US’s listings ([name_f]Canada[/name_f] does not have an accurate top 100).
I’m not normally one to care about popularity, but I that the popularity of [name_f]Sophie[/name_f] and [name_f]Isabelle[/name_f] shows that, stylistically, they’re on a whole different level from everything else I like, so I’ve moved them to the middle.
([name_f]Arabella[/name_f] just didnt feel “me” when I thought about it.)
So, what I ended up adding, [name_f]Maude[/name_f], [name_f]Vera[/name_f](family name), [name_f]Dorothy[/name_f], [name_f]Cecily[/name_f] and [name_f]Agnes[/name_f]. In the end, I guess I’m just destined to have a baby girl with an old lady name haha.
