Not sure if they grow in NC, but the location that you describe would work very well for black elderberries here. There are dwarf varieties that only grow a couple feet tall vs the wild ones that can grow over 10 ft. Blueberry bushes do well in the shade, but they will do better in full sun. Strawberries also do pretty well under the shade of apple trees. Aronia also might work for you. If you do decide to try growing grass in that spot, you might want to try red creeping fescue or blue fescue. They both do very well in the shade.

Mmqb:

If you don't have enough sun to grow decent grass, you are going to have a heck of a time growing any fruit bushes that could remotely be called yummy. Don't go to a lot of trouble building a stone wall and hauling in topsoil unless you can provide for some additional sunlight.

Blueberries might survive if you get the right acidic soil mix, but most cultivated varieties will produce very little in shade. Grapes would be a non-starter. Yes, you might be able to grow elderberries if you want to make jam, but aronia is a spitter.

You could grow some lovely impatiens on a site like that.

Most of the soil around the Raleigh area will do just fine for blueberries, but like Don says, the berry productivity will be in proportion to the amount of sun they get. My sister who lives in your area near Raleigh has healthy big blue berry plants in a mostly shaded area which produce enough berries for them to enjoy but not nearly what mine produce in the full sun.
