I've used Shotcut, it's simple and easy: https://github.com/mltframework/shotcut

I've tried Kdenlive, but honestly, shotcut met my needs, so I didn't explore it too much: https://invent.kde.org/multimedia/kdenlive

DaVinci Resolve is also available for linux. I've never used it though.

All the Davinci software runs well and I consider it class leading in its category of software.

Design, sound production and cad are all lacking strong alternatives on Linux.

Kdenlive isnt bad
