Pardon the cliché, but could you plant those vining sweet potatoes "outside the box?" If you have the space, consider putting those sweet potatoes in-ground at the edge of the raised bed so that the vines may travel through the bed but not be rooted in the bed.
I have a raised bed with some exposed soil so I covered it with the vines from a nearby grape plant then cut the vines if they get overgrown. Maybe those sweet potatoes could be planted in-ground next to the raised bed and the vines artfully moved into the raised bed gaps as needed. Sort of a compromise "living mulch cover crop" that takes no nutrition from the raised bed to grow, allows easy access to onion sets, and thrives on the "trickle down" nutrients (such as worm castings) from the bed runoff.

I've seen a lot about sowing white clover as a living mulch,but it never seems to compete in my lawn, beds or containers.

They vine and run readily.
I put some out just last month , very late in the season and they have spread quite a bit, but they don't seem to climb.
