You could try a wall shrub such as ceanothus. Dark Star will spread to about 3m and give you scented flwoers in late spring. Another is payracantha which has spring blossom and autumn berries and is excellent for wildlife.
If you stretch wires horizontal wires between the posts at 12"/30cm intervals you could try clematis such as armandii which is evergreen and has scented white flowers in spring.
