Fruit trees, apple, pear, cherry, peach, etc, all have simple toothed leaves. That is there are small "teeth" around the edges of the leaves. They are sometimes so small as to be hard to see, but they are there on all North American fruit trees.
Live oaks do have leaves with that shape, but they are much smaller. Pin oaks, actually willow oaks, also have similar shape but much smaller. There is a pin oak, but it has the common five lobed oak leaf shape with a thin pin-like spike at the tip of each lobe with a very distinctive dark grey bark.
After some more research I'm still thinking it's a laurel oak.
