For the last 8 years I've using Ubiquiti Toughcable Pro which is rated for outdoor and is UV-resistant BUT...
It's not directly exposed to sunlight, as I tuck it under vinyl siding or siding edge moldings or I put it under a roof overhang, etc. In some cases there is a few inches directly exposed where the cable exits the siding or molding and enters the structure with the drip loop and is located on a wall way down closer to the foundation. In those instances, after I caulk the cable and entrance bushing, I paint-to-match all of it. It protects it from UV and disguises the black cable and entrance bushing on the lighter colored wall or siding.
