You might check out whether a Kerria (Japanese Rose) would fit your site, purpose, and climate. It is NOT a rose, they just stuck that moniker on it.
Hortiplex link below.

It doesn't have suckers nor cling so it'd need a little help by tying at first. The flowers are bright clear yellow and quite small - the size of the last joint of my thumb. They come in single-flowered and double. I have the double and have never seen a single. I just love it. I've seen it reaching the tops of small-medium trees, like 20+ feet up but it doesn't seem to put out enough growth to smother everything. It only blooms in the spring, rather heavily, with a rare flower or two appearing the rest of the warm seasons. It likes shade, especially on the roots.
Just a thought.

Do you have enough room for a climbing hydrangea? They seem to be rather large. Have you thought of clematis?

I wasn't sure if the climbing hydrangea would get as large in my area as they are touted to. Clematis seems to be very delicate and I wasn't sure if they would like a shady location

Climbing hydrangea do well in shade but are very slow growing, mine has grown about 1/2" in the last year.

Schizophragma hydrangeoides 'Moonlight'

Clings without a trellis, and likes shade. Link below, and also you should google it for more info. Lovely plant.
