Sorry I'm not much help, I can't recommend a fig variety as my experience of Brown Turkey and one from a cutting from my aunties gorgeous tree just haven't done well in similar size pots. I'm pretty sure I noticed one of this years catalogues with a dwarf fig, just cant remember which at the momment.
Slightly off track, I have had good results with some of the patio fruit trees from Blackmoor nursery, Pear, cherry and apple. I've a couple of the peach and nectarine too but they are kept indoors to avoid peach curl. Perhaps something there to take your fancy?
