James Prigioni (one of the videos in the article) inspired me to start an orchard a few years ago. Hoping to get my first apples and plums this year, as well as a very nice amount of berries. Regarding shade-tolerant plants, I planted two kiwiberries last year (male and female) in the same spot where I had some honey berries (not mentioned on list but need 6-8 hours for best production).
Outside the wire, there’s a lot of black raspberry, I think allegheny blackberry and wineberry. I prune many of the black raspberry and wineberry and harvest those as well. The wineberry seems to do particularly well in the shade. Also probably one of my favorite berries.
