With that wall behind you have an extended growing season,
as the wall will collect/store/radiate heat both on a daily basis,
and in Spring & Autumn.
If you really want a hedge, Yew is native and a source of berries to
resident and overwintering birds. Not so good if any children will
routinely be in the garden as the leaves and seeds of the fruit are toxic.
If there is no need for a formal hedge,
install some pro-trellis and grow some currants:
black-, red-, white-
and some gooseberries which also come in a variety of colours.
They'll cope. They were developped from woodland edge plants.
Just remember to plant the young currant plants deep
to encourage additional vertical shoots,
and,
really firm down the soil.
Otherwise you'll suffer from 'rootrock' and they seem never to establish/prosper.
Ask me how I know.
