I believe (not an expert, but I read some vulgarization) that in most societies of this time, all male citizens (i.e., not slave) were supposed to be able to fight in a war if need be ?
If there are societies where there were non-slave citizens without any fighting skill, definitely yes the game should represent that fact for their in-game civilization (and it may be an interesting differentiation point to have woodless citizens that do not suck at mining), but apart from that there's no point in creating yet another anachronism.
Also, if it's possible to represent slavery in a strategically interesting and not totally icky way, that could indeed solve part of the problem as women would basically disappear from the workforce and as such from the game (save from female priests, traders and champions).
But I'm not convinced by the ideas presented so far (and haven't tested Delenda Est)...
Another option would be making women's tasks (like weaving and spinning) more prominent in the game (but of course only if there's a strategic impact, not for gaining woke points).
I don't have many ideas on how to do that in a meaningful and interesting manner, though.
