I'd say Kdenlive is pretty good. The UI feels a bit clunky and dated, but other than that it's a capable video editing software.

Kdenlive - Worked the best for me, but has the worst name.

Shotcut - Seems feature rich and reasonably good

Openshot - Seemed more approachable, a little less performant.

Blender - I've heard it includes a good video editor in there somewhere, tho I've never used that.

Olive - I think was another Foss video editor? But it might be discontinued. Never tried it either.

I used Kdenlive quite a bit. If you’re not doing anything professional or don’t have TONS of edits over 30+ minutes, it should do the trick. The reason I say this because sometimes when I have spoken audio cut frequently, the first half a second has a weird blip at the beginning of it. Sometimes they show up in the rendered video, sometimes they only show up in the preview. It’s annoying as hell to go back and try to fix.

There’s also Blender’s video editor, but, man, it has a steep learning curve, at least, for me it did.

I use Shotcut, works well enough for what I need.

You can also try Kdenlive, though I have previously had problems with it where it just failed to work at all (have not tried recently). There is also a video editor integrated into Blender.

I like Kdenlive a lot but man, why is the Export feature-- y'know, the thing that let's you EXPORT A MOVIE-- buried in some drop-down menu like it's a minor afterthought??

Kdenlive. It's a lot like Sony Vegas if you have ever used it.

Apparently the keyboard controls on Kdenlive are really good

OpenShot is FOSS and they support Linux, Windows, and Mac. They seem to be dripping Flatpak in favor of AppImage, though. So that's gross.

I tired kdenlive, openshot, shotcut, and some other one that's very old looking that I forgot it's name a few weeks ago (again) and kdenlive was by far the least frustrating one to use for me and the best looking one (imo), can't really recommend anything other than it.
