Most mainstream distros will work with pretty much all of the software suggestions. I tend to avoid recommending Ubuntu these days as Canonical have some stubborn ideas regarding things (snaps should have been shelved long ago in favour of flatpack), that said, PoP-Os is an excellent choice for buntu based without the snaps.
Video,editing: shotcut is pretty good alongside Kdenlive. For anyone working with audio, Audacity is a definite must have for track/sample editing and effects. Whilst Ardour is an extremely capable DAW, there are others you might want to check out, LMMS is a nice sequencer (fruity loops) DAW for example. On the professional side there is Bitwig (never used it but heard good things about it) and my personal favourite Reaper.
