Bit late to the party and many of my ideas have already been summed up by @kachenka and others. But a few cents:
All the names broadly fit within the two syllable trend of the last 8-10 years, with [name_f]Greer[/name_f] being a 1.5 syllable name (lol) and also fitting within the unisex/southern (US) genre that has had a very strong influence on English-speaking naming worldwide. So in some ways, they’re all of their time.
But more specifically, as others have said, [name_f]Maura[/name_f] stands out - I think because it’s a more unsettling, less cutesy name with the unusual “Mau” sound and feels even more 1950s-1990s somehow (a boomer or boomer bestowed name). [name_f]My[/name_f] only celeb association is [name_f]Maura[/name_f] from [name_f]Love[/name_f] [name_f]Island[/name_f] UK but I otherwise don’t hear the name much at all.
[name_f]Orla[/name_f] and [name_f]Oona[/name_f] seem more artsy/hip/cool-gal and most explicitly part of the current trends/ generation. They don’t seem overly popular but they do feel very “now” (or even a few years ago). [name_f]Dora[/name_f] fits but is still quite attached to the cartoon and feels more vintage and retro than [name_f]Orla[/name_f] and [name_f]Oona[/name_f]. Not sure how generational [name_f]Greer[/name_f] is - possibly more “timeless” because it’s a unisex southern name and this “trend” is less a trend and more cultural/a genre (with sisters, [name_f]Delilah[/name_f], [name_f]Adeline[/name_f], [name_f]Piper[/name_f], [name_f]Savannah[/name_f], [name_m]Rowan[/name_m], [name_f]Dorothy[/name_f] etc).
So if you want to be out if the current trends and well-known cultural genres, [name_f]Maura[/name_f] would seem to be the pick. You could even move to [name_f]Maria[/name_f], [name_f]Marianne[/name_f], [name_f]Marion[/name_f] which I think would also go with your other names, potentially better.
Speculative, but it feels like names are now moving towards and soon going to jump to boomer names so you could either get ahead of or defy that trend! The two syllable (and A ending) and diminutive names trend could be on their way out - which could be good or bad for you depending. In other words, if you choose [name_f]Dora[/name_f] or may seem quite fresh as it’s more a 15 year old name. If you choose, say, [name_f]Suzette[/name_f], [name_f]Valerie[/name_f] or [name_f]Christine[/name_f], you’ll be an early adopter of new trend coming in. Within all trends, we of course still have names (usually English/Euro royalty?) deemed classical and timeless, so that could be your safest bet - [name_f]Beatrice[/name_f], [name_f]Charlotte[/name_f], [name_f]Josephine[/name_f] etc. [name_m]Augustine[/name_m] and [name_f]Elizabeth[/name_f] got in this (and the rush of century trends). And if you like [name_m]Irish[/name_m] names, consider one without the two syllable, “cute” A ending pattern - [name_f]Bridget[/name_f] or [name_f]Caitlin[/name_f] etc.
