Just about anything calling itself "polish" is going to be too abrasive and leave it hazy. Like anything you'd polish, you might have to start out with a coarser grit but take it real easy doing so, try a finer grit first and more elbow grease if certain scratches need it.
You might laugh but use common toothpaste on a fine microfiber cloth, not the type of microfiber with the fibers sticking out but rather the flat type used for camera lenses, eyewear, etc.
None of that gettin' in a hurry with a power tool, rather slow, light pressure, and always wet toothpaste. Do not let it dry and then wipe it off, rinse off wet after final passes in the same direction, not orbital.
If you want to slow down the scratches coming back, put wax on it but not those water based synthetic formulas that dry if you don't wipe them off quick enough, rather a natural oil, beeswax, etc product and again using a clean fiberless microfiber cloth, not the same one that now has toothpaste grit embedded in it.
This is about as good as it gets, because you can't keep getting new trim pieces every other time it's washed. I really wish Ford had gone with HAIII black anodized aluminum for this, but get why they did it, wanted it to look like the black glass areas to increase the floating yacht roof look.
