Clematis sounds good. You can get evergreen ones, but mine didn't survive a frost (perhaps it wasn't big enough to survive - should have put fleece over it!) Jasmine will be pretty, haven't experience of climbing hydrangia - sorry. Also you can plant summer flowering bulbs to extend season of flowers. You don't give the measurements of raised bed, so a bit difficult to assess how much you could get into it. Always aim for quick growing plants to cover soil, chuck on a bit of bark chippings, then very little weeding is needed, plus I think it looks neater! Happy to help.
