Blueberries? They grow as an understory in pine forests, so they grow naturally in shade. They do require acidic soil, though...here in the Pine Barrens they grown in sand with lots of pine needles. I have acres of wild blueberries and commercial plants that also do well in full sun.

You could also try something in the ribes family, gooseberries, currants, or jostaberries. They will produce in bright shade, are pretty ornamental, and do not get large, maybe 4 feet.

I grow honeyberries in the shade. Seem to do okay.

All ribes family, rasperry and blackberry....American blueberries need more sun, but i think that could give some fruit....obviously the production will be reduced compared to an half-day direct sun position....

Try also Paw Paw, normally it grows in the underwood....

P.s.

Also Schisandra chinensis likes shady position
