1. Do you believe that hormones like testosterone have large impacts on a person's behavior?
2. Do you believe that men have roughly 20x more testosterone in their blood serum than women?

2. Yes.
Doesn't change the fact that most comportments and interests are mainly ruled by social environment and upbringing, and biology only have this little impact (and it is still probably less that my brain will attribute, but at least i'm self-aware: https://en.wikipedia.org/wiki/Fundamental_attribution_error).
Unless you think poor people are biologically less interested in space, earth crust, plants, sailing, horseriding, i'd be pretty confident in saying that most differences between children are in fact solely based on culture. This might evolve later (puberty hit!), but considering childhood is the crux of so much of your later choices
I've been a youth camp counselor, and in my country, classes are not always segregated when going to those camps (they are more and more tbh), and with this experience i can say: you tell me your child hobbies and dreams, i can tell you your income quintile (or social class rather, as cultural inheritance is not always correlated to income), whether it's a boy or girl, and if his family emigrated recently. Only work if you're from my country, but i'm sure if you talk to any youth camp counselor in your country who cared and worked this job for six+ years, he'd be able to do the same.

Twin studies disprove this. Separated twins, in different parts of the country, end up doing the same sort of jobs and marrying the same kind of people.
We're willing to assume different dog breeds -- all the same species -- have different temperaments, why wouldn't this apply to people. Even Dobermans can be trained to be nice dogs, but that means the training is overcoming the urge to bite.
Asserting that there are sex-based personality differences is not incompatible with gendered behavior being mostly social or learned.
All knowledge of these objects, what they're used for, and who uses them were learned from societal influences. A kid doesn't have to care about social norms to tell that most people they see playing with sticks or driving dump trucks are men, and most people they see pushing strollers and playing with dolls are women. It's like that from out in the park to within picture books.
