I would certainly recommend a small weeping fruit tree, probably a crab apple. Mine is currently an abundance of two toned pink blossom, attracting lots of bees.
I haven't had much success with growing a climbing rose in a container, but the location wasn't perfect, so moved it to a sunnier spot and planted it in the border and it's now romping away. If you google 'climbing roses in containers uk' and go to the rhs site, they recommend 10. You would need a very large container, though. Interested to hear what you choose. Enjoy the search!
