Can you attach wires to your fence? Solanum album is evergreen and has white flowers all summer. Quick growing but easily pruned back.
Check out Lonicera Baggesons Gold. It's fairly quick growing, fits your dimensions and has beautiful olive leaves in winter turning butter yellow in spring and summer. No flowers,but lovely thing.
Taxus Stamdishii is beautiful,conifer that would thrive there.....occasional red berries but no flowers
The ceanothus is a problem....the bigger varieties are the most tender and any that grew to height you want will also grow just as wide......and suddenly die on you.
Photinia would grow there too....colour from leaves.
But, holly is my choice. Ok, no flowers but golden king has yellow and green foliage, red berries and looks good all year round
