..I agree....nooooo...lol... in that I didn't like many of James's choices, or at least I don't have any experience of them which is more to the point...
..my choices would be:
Sorbus 'Joseph Rock'
Sophora Japonica 'pendula'
Eucalyptus if suitably pruned
a Cornus kousa variety...
Cotinus 'Grace' which can be trained as a small tree
can't think of any others offhand...
