The citrus should do well in pots. I've kept a number of citrus trees
in pots for over 20 years. You will probably have to repot into
larger pots every year or two until you get to a 10 or 15 gallon size.
Just take them inside if there is a possibility of a hard freeze.

There are a number of genetic dwarf fruit tree varieties, particulary
genetic dwarf peaches, that should do well in pots also.
