I think there is a grain of truth in OP's argument, I'm not sure how much of it is deliberate, or if there's really any political agenda behind it:
Lae'zel - female (primarily) Strength based class, frontliner - likes to get close and brutal
Karlach - female (primarily) Strength based class, frontliner - likes to get close and brutal
Minthara - female (primarily Strength based class, frontliner - likes to get close and brutal
Jaheira - female (half) Strength based class (Dexterity probably better) - likes to get close and brutal
Shadowheart - waifu material
Gale - male (primarily) non-Strength based spellcaster - sit back and pew pew. Gets in trouble with the dommy mommy that he simps so hard for and she literally tells him to kys.
Wyll - male (primarily) non-Strength based spellcaster - can pew pew but can fight close. Gets in trouble with the dommy mommy that he simps so hard for and she makes sure he gets punished.
Astarion - twink
Halsin - bear
Minsc - too late in the game
This is my gripe too. It's fine to have female fighters and male casters. But... no male STR characters and a whole 4-5 female ones? It just becomes painfully obvious. I like competent semi-aggressive/confident male characters and there are none. Plenty of female ones though. And I find the female disposition to be somewhat on the confrontational side, while the guys are just out to make nice. It's... weird.
The combination of races, classes and genders really seem out of whack in BG3.
