If you do decide on cherry, apricot, apple etc it is worth considering the rootstock for each kind of fruit. Here is the advice from Keepers Fruit Nursery.
Apple
Pots and planters. Contrary to what may seem logical, medium vigour rootstocks such as M26 or MM106 do better in pots than more dwarfing rootstocks. Restriction of the roots by the pot will keep the tree small. It is also best to start with one year maiden trees.
Pear
Pots and planters. Both dwarfing Quince C and semi-dwarfing Quince A rootstocks can be used. Restriction of the roots by the pot will keep the tree small. It is also best to start with one year maiden trees.
Plum/Gage/Damson/Cherry plum/Bullace
Pots and planters. Both VVA-1 and WA-VIT rootstocks would be suitable. Restriction of the roots by the pot will keep the tree small. It is also best to start with one year maiden trees.
Cherry
Pots and planters. Semi-dwarfing Gisela 5 rootstocks. Restriction of the roots by the pot will keep the tree small. It is also best to start with one year maiden trees.
Peach/Nectarine/Apricot
Pots and planters. Semi-dwarfing WA-VIT rootstocks can be used. Restriction of the roots by the pot will keep the tree small. It is also best to start with one year maiden trees.
The final choice is yours but remember to feed them occasionally.
