I think your situation sounds good to go.
Mulberries, persimmons, raspberries, blackberries, grapes
should produce annually, no problem.
Peaches would be a good choice. Apples and pears too. I might skip cherries and apricots for now to see how the others do.
Nuts are trickier in your situation. Maybe chestnut if soil is a bit acid.
In any event, a frosty pocket in NC zone 7 is still plenty warm. Look for varieties that break bud late.
Your site sounds very workable for your objectives. You'll get fruit way more than once in five years if you select good varietals.
