I've had success with grapes, kiwi, passion fruit and jasmin on fences, although I'm not sure if you can grow these at your altitude. Blackberries and raspberries work well too, if you regularly prune them back. To contain them you could plant them in a large solid container inside the soil to create a barrier, similar to what is sometimes done with running bamboo.
One of my fences has grapes intercropped with lavander and a few roses. Then this gets some small annuals added in rotations (herbs and onions mainly) completed with flowers.
Morning glories were not such a good
experience, they climb fast and are absolutely gorgeous, but very invasive.
