Thoughts on r/K selectivity within humans

Yes.
Sub-saharan Africa is primarily r-selective.
Pretty much everywhere else is K-selective.

It's a relative scale. All humans, even Africans are K selected when compared to fruit flies. But within human society, brown cultures have relatively r attributes while light skin cultures have relatively K attributes. But even within these groups, there are subpopulations that have r or K reproductive strategies relative to the group at large.

Have you ever met Mexicans? There's a few k type societies in south America, but most Latinos just shit out child after child and then look for the US to pay for it.
