Currently I have none, but will probably plant one or more in the early spring.

The last fruit trees I had were one each of two different varietals of peach trees which produced at different times. At their peak I had way more peaches than I knew what to do with even after culling about 2/3rds of them when they were marble sized. Even with canning and making every peach dish I could think up, I was still giving away most of them. I suspect the stone fruit trees are all going to produce over about a 3 month period even if you get varietals that produce at different times. That’s going to be a lot of work harvesting everything and dealing with them. I’m guessing with that many you plan on selling them at a farmers market. Otherwise you’ll easily be overwhelmed.

Cherry trees are a lot of fun and might be worth considering. It’s rather nice to pick and eat them immediately while they are producing.

Most whom live within easy walking distance of me and my wife.

at least for me they seem to be more vigorous and prolific than plums

but obviously I'm wrong.

And would seriously have considered them had they been suitable for my zone.

So from growing pretty much nothing...we now have apricots, peaches, nectarines, pluerries, pears, asian pears, plums, pluots, apples, cherries, blueberries, blackberries, raspberries, oranges, grapefruit, lemons, limes, mandarins, and figs. And pomegranates.

I've had zero luck with kiwis and avocadoes and currents.

Bananas went crazy and I pulled them out.

but I found it really helpful in our planning.

If not, don't expect any fruit for about 7 years. The elderberries will begin to produce in the 2nd or 3rd year, but again, expect about 7 years for a good harvest. Elderberries have a tendency (hahahaha) to take over, so leave room for that. You can dig up roots, cut down shoots, whatever, but they do not believe in staying in boundaries.

Raspberries, blueberries, blackberries, strawberries are more immediate and produce after a year or two.

Good luck. I'm still waiting for cherries from my trees and when they come, they are going to be divine!

My goal is to have a garden and orchard that can provide produce for my immediate family, most of whom live within walking distance, for years to come and long after I'm gone. My family history suggests my time is very short, I'm 61 now, or I have another 25-30 years in me. It's one of the two.

Thanks for the tip on elderberries. I may rethink having them or maybe consider putting them in another spot in the yard further away from the vegetable garden and orchard.

starts to others to keep them under control as well. I do mow them under in a few places.
