I don't know of a fruiting tree that can tolerate full shade. Even the Paw Paw tree requires at least dappled shade so that the leaves can get some sun and the older these trees get, the more sun they want.
All the other fruit trees do best when they get at least full morning sun. Pears, Figs, Apples, Peaches, Plums, Mulberry, Cherries, Orange, mango, kumquat, grapefruit, lemon, lime, all need a minimum of 6 hours of sun per day to thrive.
If any of these fruit trees can survive full shade, they will most likely never bear fruit since fruit production is part of the photosynthesis process of the trees.
Even were you to get fruit set, the tree will drop all fruit that it can't support through the photosynthesis from the leaves.
I have two plums that get afternoon shade, they are not growing as robustly (read barely growing) as the full sun trees in our mixed orchard.
Service berry, Blue berry, might be good choices the service berry can grow to 20 feet and does best in dappled shade, the high bush blue berry does likewise.
Neither of these will do their best in full shade, but they might grow enough to create a screen.

Thankyou for this informative info!
Yes the juneberries was something I was thinking about trialling . They are rare and priced accordingly unfortunately.
The thing about these expensive berries is that they are fairly easy to propagate so if you buy one and get it going well, you can take cuttings to create as many as you want.
True it may be two years or more to be able to get enough cuttings to fully supply your needs, but you will end up with what you want and could most likely sell the surplus.
My vineyard is going to be built from the vines I already have growing now so my cost is held to the purchase of the five vines I started with, the rest will be propagated from these initial vines.
