"Vinegar - Tube Cleaner" blocks all YouTube ads in Safari.
It also replaces YouTube's video player with the native HTML5 player, so you can play videos in the background or watch them in picture-in-picture mode.
Vinegar can also be used together with Sponsorblock for a completely ad-free experience. It's a difference as night and day.
