Women and men

peace,
I wanted to ask your opinion about the differences between men and women. Do you think that the difference between them is created only from social constructions and thought patterns of many years (the implication of such a perception is that everything is changeable, meaning that a man can completely become a woman in terms of consciousness, emotion, etc. if we just change our thought patterns)? Or is the difference "built-in", meaning that there is a fundamental difference between the (soul) of a man and the (soul) of a woman, a difference that did not arise over the years but rather a difference that is inherent in us from the moment we accept our gender identity?
I would love to hear your opinion and, if possible, provide sources (not necessarily from Judaism).
Thank you in advance.
