Compact fruit tree recommendations

Hello all,

I'm still quietly plotting my new garden, particularly things I can be doing when I (hopefully) move in, as that will probably be October/November.

I do fancy putting in a couple of fruit trees. However, it's not a big garden and they will have to go near the south end of the garden so that they are well away from the house and the garden retaining walls. I think I'll be wanting something on dwarfing rootstock so they don't cast too much shade (though a bit will be good as I think the garden could be too hot in summer) and don't take up too much space.

There are just so many choices and I don't know what to go for! Ideally, I'd like something that will give decent harvests (for a single person, not needing to feed the nation!) within a couple of years as this isn't going to be my forever garden. I'd prefer something that doesn't need too much fussing over, and obviously, taste is very important! I'll probably get a separate fig tree in a container (my previous one died while being babysat by my mother) and rather fancy trying a peach in the greenhouse, but need to do a bit more reading on that.

I'd love to hear your suggestions about the trees you have in the ground or would like to have. I'd love a greengage but couldn't find anyone selling them on sufficiently dwarfing rootstock, so maybe a nice dessert plum? Any good apple recommendations? I'd like a cherry, and don't think a small one would be too much of a hassle to net from the birds, provided I didn't accidentally trap them very often (my Mum stopped netting her fruit bushes for this reason). Dessert cherries and sour cherries both appeal. I don't fancy a pear tree so much, but maybe that's just because I'm used to mealy supermarket pears?
