Just to note here, resolve is also much better than premier, even the free version. Considering the Adobe pricing, buying studio for $300 is a better decision imo.
kdenlive is solid for the simple cut/fade type of work.
I’d also add something I’ve mentioned elsewhere for pictures - in case of raws, paint.net is ok, but imo darktable+krita is a much better experience.
Pretty much everything is available in a package manager, flatpaks, etc.
If you’re at the point of building from source, I don’t think you’re in regular user territory to start with.
