I recently used Lightworks on Linux. It worked fine. Quite a bit more powerful and hence complicated than the tools I used before.

It's proprietary and the free as in beer version is limited to 720p mp4 ("YouTube") export, which was sufficient for my use case.

DaVinci Resolve free edition also looks nice: https://www.blackmagicdesign.com/products/davinciresolve/

The tool started to work on color, but it looks like they've made a decent editor also.

I was a paying Pro customer for Lightworks but when I had a very important and conceptually simple project come up - conversion of a large archive of globally unique, 8mm film reels that had been pre-digitized in to cut and labelled portions - the software couldn't cut the mustard and they literally came back to me with a reply like "that is not our use case".

The content was super important stuff - early footage of many areas of the world not otherwise filmed - and was destined for Wikimedia Commons.

It was the worst experience I've ever had with commercial software since Windows 'corrected' an NTFS volume in ~2005 and nixxed the lot. From memory it was something to do with the input codec (beyond my control as lossless was a requirement), the output codec, and the aspect ratio. The software just couldn't cut the stuff. I was left to go back to ffmpeg and VLC. I will never again waste time learning a commercial UI.

Lightworks is a good editor but I found its performance on my desktop on 1080p footage could sometimes be worse than editing 4k footage with Final Cut Pro on my macbook (that could be because FCPX generates proxies but I'm not certain about that as it seems very fast scrubbing through footage even when its still on my SD card. FCPX is also amazing at accepting most video formats and dimensions. Good luck getting Lightworks to do something unusual like export at a 1:1 aspect ratio for instagram.
