If you don't mind "wild" there are a lot of things. Research the native species that grow in your area that provide fruit/nuts. I am in 6B and for us those are blackberry, black walnut, black cherry, some forms of raspberry, wild strawberry, elderberry both red and black, white oak, chokecherry.
If this is completely no tend then look to spend some time originally cutting out invasive species that could overwhelm the ecosystem and cause natives to struggle. Best of luck!
