I think we now have enough information for a master settlement plan.
Here is my initial proposal to start the discussion.

In my opinion the two copper sites are prime locations due to the multiple different resources found at each, and we should consider stretching our reach to grab them while the grabbing is good. While it's true the western site would face cultural pressure from Spain, I think it wouldn't be in any imminent danger of flipping. If they're the target of a future war, depriving them of copper would potentially deprive them of spearmen to counter our horse archers. The northern site, having elephants and gold, would give us two luxuries to raise the
cap on our cities, in addition to the copper for better weapons.
