Hedge?

What to plant along the property line?

The wall runs more or less northwest/southeast.  We´ve never met the neighbor and have no idea of his plans.

more complete

What won´t undermine the wall or shade our side too much, but will screen and also provide something useful?

Espaliered fruit
Blueberries or soft fruit
Hazel
Grapes
Roses
Lilac
something else?
