If you haven’t already, ride around and scout productive yard trees in the area. Stop and ask folks about them. I do this and have never gotten a cold shoulder. Talk to the county extension agent and ask about “bombproof” trees that just do well in the area no matter what. They may be just a shill for big ag, they might be awesome, or something in between. No way to tell until you chat them up.
Identify EVERYTHING on your property. You may have some incredible stuff growing already. This is much easier now than it was a decade ago with apps like I naturalist and google. Be sure to cross reference if you are not sure. A 5 or maybe even 10 year old persimmon around here looks like a sapling. Cut it down and you just backed up quite a bit.
Most nut trees are a long term prospect. If they do well in the area, I would plant 3-4 for the next generation then focus on trees with faster returns. 15+ years in, out of 50+fruit/nut trees, mulberries and pears have been the only two that have produced enough to bother with preserving. Several of the others have produced a yield, but couldn’t really call them a staple at this point. Various bush/bramble berries have produced well on a shorter timeframe, but are labor intensive picking and require more maintenance to keep weeds at bay.
Off hand, if I was deciding what to do with 1.6 acres, I’d probably put the closest (zone 0-1) .25-.5 acre in veg, herbs, berries, mushrooms. The rest I’d plant out in fruit/nut trees, paying close attention to final sizes and spacing. 60-70 ft spacing looks huge when you are planting a little nut sapling, but they will fill it over time. Crowd them, and they will suffer. Better to infill with nitrogen fixing trees that you harvest for
