All the ones that keep getting recommended have a UI like a cockpit of a Boeing 747 (kdenlive, shotcut, openshot, DaVinci resolve) which is so overwhelming, all I want is just make some cuts, blur a face, or something on the screen, and maybe add some subtitles.
I just want something simple, I am not gonna make the next Avatar movie.
I have a feeling there is nothing like this on linux but hey maybe one of you actually knows of one.
Blender has a video editor as part of its suite. If you are not familiar with video editing software there are a lot of tutorials on YouTube to get you started. Otherwise the building blocks are there and you can build off of your previous knowledge and likely get the results you are looking for.
