That has always been a pretty classic combo on cheeseboards. Probably that is why they came up with the idea to put it on pizza. My favorite pizzeria has it on the regular menu too. They make thin slices of halved pears for it, so the pear is not raw after baking.
Vanilla ice cream and/or raspberry sorbet topped with pitch black, salty sweet licorice sauce. (common only in Denmark afaik)
“Birnen, Bohnen und Speck”, a stew made from pears, green beans, bacon and a herb called satureja/savory. The pears in this one are a certain old breed, that is pretty hard and sour before cooking. (This is a local delicacy from the city of Hamburg in northern Germany)
Watermelon and feta cheese, especially during hot summer days (common in mediterranean countries)
Pickled cucumbers and feta cheese (those are eaten as a combo around the black sea afaik)
