"games that market is mostly concentrated on is the single category that still does not work on Linux."
All of the games you described have and will work on Linux perfectly fine under proton, it is the developers CHOICE for these games not to work.

Yeah. That single category is "games that the devs have done the extra work needed to make them not run in Proton". There's no consistent game genre, age, or intended audience... it's just whether or not the dev decided that running on the Steam Deck, SteamOS, and the various Linux distros was something that they were actively going to block.

[0] An illustrative case is Apex Legends. It waffled back and forth between "permitted to run under Proton" and "not permitted", and eventually landed in the "not permitted" bucket. And no, "'competitive' shooters" is not the category that this fits in because shooters like Hunt: Showdown and Counterstrike work just fine with Proton.
FWIW, Valve doesn't require use of that system for tournament play and is of the opinion that VAC is sufficient to run a Counterstrike tournament. [0][1]

Can you blame them if the choices they have are a) support Linux but with weak anti-cheat, or b) exclude ~3% of PC gamers?
There was also a huge regression from CSGO->CS2. There used to be a feature that would not network players if you could not see them, this was completely scrapped and now cheaters can see where you are at all times meaning that if you are closet cheating, you can always have your best player follow the bomb.
Pretty much any service with a strong client-side anti cheat then relies on manual bans for people who slip through the cracks which is the most effective system for dealing with that.
CSGO had the overwatch system but that was pretty useless for all but the most blatant cheaters
