Any tree species can be used to grow a Bonsai from. This of course includes fruit trees!
Bonsai are kept miniature by applying techniques like pruning, wiring and repotting. Over the course of several years the leaves slowly reduce in size, which is crucial for the tree to appear natural. The fruits however often remain quite big. Tree species like the apple or lemon tree for example have quite big fruits, which can appear dramatic but perhaps a bit artificial. Other tree species, like the crabapple or pomegranate have naturally small fruits.
The most popular fruiting Bonsai trees are the Crabapple, several Citrus varieties, Olive trees and the Pomegranate. But you could also try the Blueberry, Cherry or Quince.
