for simple editing though I used to use KDEnlive a lot, pretty easy to wrap your head around, allbeit with a few quirks that take some getting used to ( https://kdenlive.org/en/ )
I'm sure theres others but those are the two I've used personally.
Heavily agree. Imo both resolve and KDEnlive are capable of very complex things so might appear as though they are complex to use, but they are only as complex as the thing you're trying to do. If all you need is cut and move, they are dead simple.
