YT on Firefox Mobile has the added benefit of letting you swap to desktop mode and play videos with the screen off, no YT Premium needed ;)
Been doing this for years, but if too much of a hack for you, NewPipe also supports background video, and downloading video, or just the audio, which is great if you have a lot of long form audio-focused channels like music reviews, videoessay content, etc.
