Having read the paper it seems that the strongest, most consistent differences are in mate-seeking ("introduce me to potential romantic partners") and emotional support ("reach out if I'm having a bad day").

The other stuff you mention, social information ("tells me when someone says something negative about me") has basically no consistent difference between the sexes.

And to answer your question I definitely think there is some biology involved. Like most of this stuff, cultural builds on that and creates even more structure.
