CLEMATIS MONTANA

Will this grow on a north facing fence and provide some protection to
the fence?

Well, it will, but it will climb over the top and flower up there.
And, as Franz says, it will probably bring a weak fence down. A
better clematis for a low or weak fence is C. alpina, which responds
well to being cut right down after flowering.
