I think the reason Cavendish is the main crop is because it can survive shipping and handling well. Most varieties of bananas can't.

And some of that Cavendish preference is strictly cosmetic. Some varieties will blemish easily but still taste great inside for a while, while Cavendish blemishing means you’ve got 1-2 days tops to consume it.
Yes.
Also also, Cavendish is a "dessert banana". Most banana varieties are more like plantains -- they're savory and are usually cooked.
I have nothing to cite but, just based on their ubiquity, I would bet $5 against the hole in a bagel that Cavendish bananas produce more per acre than any other variety.
