I don't think it's a social construct, at least not totally. I think the process of human evolution over the past hundreds of thousands of years has definitely had a hand in putting men and women into specific roles. As a result, women on average tend to be childrearers and caregivers, and men on average tend to be providers and protectors. We see that reflected today in people's chosen careers, where women dominate fields like nursing and childcare and men dominate fields like agriculture and security.

As for gender aesthetics, where there are differences between how men and women dress or act or carry themselves, I think that's much more of a social construct. Though I do think there are faint echoes of our evolution to be found there as well. E.g. men's clothing tends to be more about function and women's clothing tends to be more about form, which is somewhat in line with our evolutionary roles.

But we live in a much different world now than our ancestors. Gender roles are no longer critical to the survival of the species; we've transcended beyond that. And I think that's part of the problem because while gender roles serve less of a purpose now, they are still kinda programmed into us, and that is causing a lot of confusion.
