This surely is a very large and lovely vine!
The size you need is a very tough one indeed, perennial vines have one purpose in life, and that is to GROW - so pretty much most anything is going to have to be regularly trimmed. There are some perennial vines that might do for you but won't be evergreen.
I do not know if creeping fig would work OK - it depends what kind of utilities are being hidden, and what the trellesing is made out of. Mostly creeping fig likes a solid surface to go on.
