I don't want a commercial enterprise, I'm too old to start that now.
I have two apple trees which will be plenty for my needs (and the birds) - they were gifts from my kids so they'e not going anywhere; and three bramble bushes, that are babies just now, will I am sure be fine in a year or so, and to be honest if they want to rampage along a fence they can feel free, the grass will either be cut or trampled by dogs.
I would like varieties of cherry, plum, and blackcurrant, and maybe gooseberry too. Mainly it will be an area to wander through with the dogs on fine days, or look over from my verandah; and to pick fruit as it comes around, sit in various seating areas (or as we call them in Aberdeen 'sitooteries'), and listen to the birds and watch the squrrels
