The most low maintenance tree for fruit production is the fig tree. It wins by a wide margin. Figs don't need a pollination partner and rarely get diseases. They need almost no pruning and produce heavy crops with minimal effort from you.
My fig tree is the one plant in my yard I spend the least time on. I don't spray it at all. I don't worry about pollination either. I remove a few dead branches each February and spread a layer of mulch in spring. That's the entire maintenance plan for a tree that gives me two crops of fresh figs every year. Compare that to my apple tree, which needs annual pruning, dormant oil sprays, fruit thinning in June, and a second tree nearby for pollination.
The gap between low maintenance fruit trees and high maintenance ones comes down to four factors. Figs pollinate themselves and resist most diseases. They tolerate poor soil and fruit on new wood without shaping. Apple trees fail on all four counts. They need a second tree for pollination and attract scab and mildew. That gap turns into dozens of extra hours of work per season.
Several other easy care fruit trees work well if figs don't suit your zone. Persimmon trees attract almost no pests and grow in zones 5 through 9 with no spraying. Mulberry trees grow fast and shrug off diseases with ease. Pawpaw trees grow wild in eastern North America and have no major pest problems. They produce fruit with a tropical flavor in zones 5 through 8.
Your yard might not work for figs if you live in zones 4 through 6. In that case, go with a persimmon or a mulberry. You'll spend less than 30 minutes per month caring for either one during the growing season. Compare that to a peach or cherry tree that needs your attention every single week during summer.
You can also cut the work on any fruit tree by making smart choices at planting time. Pick disease-resistant varieties that match your exact zone to avoid cold damage stress. Spread 3 to 4 inches of wood chip mulch around the base to cut watering needs in half and suppress weeds. These two steps alone make fruit trees minimal care compared to varieties planted in the wrong zone or left with bare soil around their roots.
When I first started growing fruit, I spent hours each week spraying, pruning, and fussing over a peach tree. It still got brown rot every summer. Then I planted a fig tree next to it and did almost nothing. The fig gave me more fruit with less work than the peach ever did. That contrast changed how I think about tree selection.
You should also think about what you'll do with your harvest. Figs taste best fresh off the tree and they don't store well for long periods. Persimmons hold up better after picking and you can dry them for year-round snacks. Mulberries make excellent jams and preserves. Match your tree choice to how you want to eat the fruit and you'll get more value from your low-effort harvest.
If you want fruit without the fuss, start with a fig tree in zones 7 through 10. Pick a persimmon for cooler areas. Match your tree to your conditions, mulch the base, and step back. The less you interfere with these natural producers, the better they tend to do for you.
