I don't have experience with any of those, but I have used ShotCut [1], which is free an open-source. It works well enough on those rare occasions I've needed it (e.g. editing a video of my child playing an instrument for their class). If you're looking for "FOSS" and "easy to use" ShotCut might be worth looking at.
