A couple of years ago we visited a group of open gardens and one had very similar dimensions to your. Nearest the entrance to the garden a path started and wound its' way from one side to the other of the garden to end in a sitting area completely secluded and painted shed draped with climbers. The planting was a mix of tall & small shrubs, that generally hid the fencing. The shrubs were kept tidy in their spaces by careful pruning, some shrubs having no lower branches to create space for other plants. The scheme was held together by plants dotted along the path of two colour,s silver and blue. The garden even had a small sunken area and there was also bamboo among the planting! We have been to many gardens but this one always comes to mind as one where the owner triumphed over a fairly difficult space.
The Euonymus in the bottom picture is a plant I value in my garden. I have it climbing up a wall and also up chunky trellis. It can be clipped hard, gives colour all year round and has fluffy cream flowers when established. I think the next picture up might be a Magnolia? and the next picture up possibly from the Privet family - if it is it is a good one to clip, I have a golden type clipped into a 'tube', but need to cut out where it tries to revert to green leaves.
Thinking about the light in your garden you might be able to colour the fencing with one of the lighter coloured paints available to reflect light back into the garden? And your idea of raised beds is a good one, easier to weed, we have made ours out of decking boards lined around the depth with used compost bags - dark side out, cut & stapled to the inside of the decking boards and the filled. Works a treat, and is strong enough to contain the soil. I agree I would put the raised beds where they can get as much open light as possible to ensure maximum growth and, if you grow fruit/tomatoes, maximum ripening.
