I think what’s more interesting from those charts isn’t just the divergence between genders - it’s that (with the obvious exception of S Korea - what on earth is going on in that country??) men’s attitudes have slightly trended more conservative whereas women’s attitudes have radically changed to more liberal.
Native English speaker here - my English teacher at school always used to say that in order to write well, you need to read well.
That probably doesn’t help you in the short term, however! But, yes - finding “good” authors you enjoy is a good way to go.
