Did a speedy japan wiki scan of mostly just girls i noted down as the ones i like.

Kerria is high single dmg, drain, no boss debuffs,
Mei Plumblossom is high single dmg, no boss debuffs, fills light gauge,
Cherry is debuffer but didn't note down if high single dmg,
Sakura is high attack buffer on boss and high single dmg,
Lycoris is debuffer,
Mistletoe is counter-attack,
Helenium too (thou I didn't note her down as one I like scene off, maybe cause it wasn't uploaded or maybe cause didn't like it),
Orchid Wydler is also debuffer and like Helenium I didn't note her down (thou I like her supposedly other two 5* forms),
Pumpkin is dodge,
Daisy and Cactace aren't either of those (aka counter or debuff),
neither is Ardisia thou she has solar blast dmg buff.

Welp do have a bit of time to decide

EDIT:

BTW its my first voting event in FKG, how the after event gacha will work? Is it good idea to store 50 FGs for it, or can I just splurge on priority gacha right now (kinda like how Poppy looks).
