I haven't seen any difference between a cheap filter and an expensive one. Some of the more expensive filters are almost impossible to clean and keep cleaned. I can't remember the brand, but those were not fun filters.Just make sure they're clean when you buy them and no worries.
On a similar subject, I've had a number of lenses over the years that had serious scratches and coating issues on the front element, and sometimes on the back one too. Had one lens w/ a deep scratch in the center of the rear element, a Leica R 90 Summicron that had a rear element that looked like it had been sand blasted on the side that faced inwards. They all gave images just like the clean ones. Fog/haze/fungus will be the real problems, that's difficult to overcome w/o a good cleaning.
You can use just about any filter on any lens w/ step rings.
