I live in the suburbs west of Chicago, also zone 5 and pretty much the same climate. To my knowledge, most fruit trees, including apples, cherries, peaches, pears, plums, and apricots grow just fine here. My aunt had a peach tree and it did fine, and we've grown cherries, pears, and apples.
It takes longer for a full size tree to start producing fruit than semi-dwarf or dwarf fruit trees, and it takes another couple years before they produce well. For zone 5, you do need to plant in the spring instead of fall.
You can often get a bushel of fruit per dwarf or semi-dwarf fruit tree about 5 years from planting. It can take 8 years before standard size trees start producing, and a couple after that before they are in full production, but they should produce twice the amount (or more) than a dwarf tree does.
Spacing also depends on whether you grow standard, semi-dwarf, or dwarf trees. Most fruit trees will need yearly pruning initially in order to shape it and get it producing properly, but once they are mature, all you need to concentrate on is removing dead or damaged branches, branches rubbing against each other, plus ones growing toward the center of the tree instead of outward, to help air circulation.
If you can give more details as to what you are wanting to plant, we can be more specific. Hope this helps.
