There could be a small element where a wider cultural diversity, in that kind of situation, yields a wider variety in products, goods, services, etc., but that is very much contingent on those cultures actually promoting good, useful, positive habits and interactions.
I'm reasonably certain that hypothetical positive results of that sort though are pretty uncommon, even in the wide range of historical examples one can look at. Especially when said immigrants are imported because they have nowhere else to go (refugees) or because of political plays, particularly since either of these kinds of instances tend to import them in larger numbers than could offer any benefit.
given their geographic location, the only way they could avoid diversity is through force. doing so would have stifled trade to the point where they would not become the hubs that they were destined to be.
But they're not successful because they're diverse. The success came from the location, and the original people in charge.

Indeed, but they are also successful despite being diverse. The point is that diversity does not determine success one way or the other.
they could've been even more successful without diversity
impossible.
