>Black people (specifically this means people in the US who have dark skin and whose ancestry is in the US)

So dark-skinned Africans aren't "Black"? (But they are "black"?)

Why not just use black/white for skin tone, and African-American for "people in the US who have dark skin and whose ancestry is in the US"? Then for African immigrants, we can reference the specific nation of origin, e.g. "Ghanaian-American".

African-American includes Americans of African descent that nevertheless are not descendants of Africans that were slaves. I suppose this is a reason.

I don't think that's how the term is used.
