first time permaculture plant and fungi recommendations

This project is taking place on my grandparents’ property just outside of Hood River City Oregon. This year I will focus on the soil i.e. using wood shavings and grass clippings as mulch and propagating ground cover like clover. The area used to be a apple orchard 40 or so years ago so the soil should good for the trees I plan on planting namely apple, peach, and plum trees. What I’m asking for help with is recommendations on the under brush and other fruit trees that will do well in my area. If possible I’d prefer the plants to ether be edible or medicinal. I also have experience in growing mushrooms I am currently trying to propagate morels in a different area on the same property so if there are any fungi that would help the food forest that would be appreciated.
