Video editing for years have not been an option for Linux.
Sure there are programs, but they often crash, often encode x times slower than corporate paid crapware.
For this, you have to talk to the people you are buying your hardware from. They are getting your money, not linux. They are also supporting that hardware under Windows, not Microsoft. Tell them what your needs are, and vote with your wallet.
> codecs, media support
Funny; for years, I've been installing ffdshow (ffmpeg-based codecs) into Windows to have decent codec support in Windows; even today, many users still install VLC (or mpc, mpc-hc, mpv, mpv.net, or other clone) to get media playback without any issues.
Hardware, old to the newest, works the same or better on my Dell, HP and Lenovo machines and has for close to 2 decades.
