Are you looking for interior products that are available over the counter?
yes if you know of one, there seems to be two different textures on the door/dash areas one seems to be vinyl and the other plastic right? Ive never found anything that brought the black back.

For the outside bumper plastic piece it may be cheaper to sand and paint or add sealer. I enjoyed doing my headlights in a similar fashion and they've looked new for half a year now.
