Yeah that's a weird one isn't it? Like, you want to have female warriors, cool, please do, but for some reason you can't envision them using melee weapons and armour (even though you don't need exceptional strength to use stuff like spears, lighter polearms or even sharp slashing swords and be pretty dangerous with them), so they give them "easy to use" (lol!) bows? I wonder where this odd convention originated. Is it derived from "skinny" elves using bows in fantasy or something? Or is just working backwards from guns = dangerous regardless of user = ranged weapons = dangerous regardless of user? Crossbows would make more sense with that logic (and they really were incredibly dangerous - a child with a crossbow killed one of the French or British kings at a siege, I forget who), but crossbows are less "cool" than bows.
Not all fantasy is equally vulnerable - I notice the warrior-women we've seen so far in WoT for example mostly use spears and slashing swords (though I think that's more to do with the culture they're from rather than intentional).
The biggest historical/fantasy "nitpick" is beyond a nitpick and into a full-on trope though - all pre-modern armour is close to 100% useless in close to 100% of historical and fantasy.
