Hydrangea petelioralis is an interesting climber and may be worth investigating. Its deciduous but has attractive leaves and large white flowers in summer. We have one on a north facing wall and the nest box in there is occupied every year by robins or blue tits.

Parthenocissus henyrana is good for a very large wall as it is very vigorous, Hedera will do well but is boring. If you can give support, Clematis montana forms will do. Depends what you mean by large.

Morello Cherry will grow on a north wall, as will some shade tolerant roses and clematis.
