Running UF-B along the outside wall of the house
Since your UF cable is marked "Sunlight Resistant", you can run it outdoors aboveground without protecting it from the sun's rays.  Go ahead and make the run -- just make sure the cable isn't in a position where it could get weedwhacked, run over, or otherwise physically damaged.

If it is, you'll need to protect the run with a length of conduit.
