Well males and females and non-binary people definitively have dimorphic brain structures starting in the womb, as a result of the hormone baths they’re subjected to. Unless there’s a secret society of oppressive patriarchs born like fungus out of amniotic fluid in mother’s bellies, socialisation can’t explain foetal brain differences, not when they start before any social interaction occurs. This explains why boys and girls show different interests starting from birth, with boys more interested in structures and building stuff, and girls showing more interest in interpersonal relations and faces, hence dolls. There was a study that found female chimpanzees had the same interest in dolls as human female infants, and hormones affect brain structures in foetuses throughout the animal kingdom. It doesn’t make sense that in 60000 years of human evolution, sexual dimorphism and evolution would produce sex differences in the bodies of humans, but not in the brain, the feedback centre for the entire body. 

But all that is just like the first chapter in people’s identity. It’s nothing to get hung up on because humans are evolved enough cognitively to override that kind of biology, and there’s enough variation in hormones and brains for there to be plenty of outliers. Plus, things like careers and science are subjects wayy beyond what our brains and bodies were built to consider, so after an early point, it’s more evolved issues of choice and hard work at play; it becomes more about what we fill ourselves with than what we were pre-filled with in the packaging. Plus, what we actually accomplish isn’t just a linear reflection of the brain; it’s based on actions and choices. Boys can be just as empathetic and interpersonally successful as girls, and girls can be just as technically proficient and scientifically trailblazing as boys, and everyone has the potential to be a trashy mime with a resume of bar mitzvahs a mile long. Another example is it makes more sense reproductively for humans to be non-monogamous, and people’s sex drives are built for it, but out of choice many people have very successful monogamous relationships. Basically, people can choose to be who they want in the end, but sexual dimorphism in the brain is real, and explains certain correlations in interests.
