My thoughts is make the characters first there backstory and everything then roll for gender, as if I did gender first I would feel like I draw more towards stereotype of that gender. As one gender does not define who someone is. And this way they all seem more diverse and more alive that way.
Try different ones out. I personally avoid Lemmy.world as there more pro capatilism and Oligarchy then other instances. And tend to block instances that are against capatilism and Oligarchy.
