Frame rate and optimization issues currently leave CS2 anything but playable on Steam Deck, but it appears that Valve is working quickly to fix things.
Some games have controller-based matchmaking, where you hop in a lobby and only people with similar controllers to your get matched against you. So if you play with keyboard and mouse, you play against keyboard and mouse players. If you play with a controller, you play against other people with controllers. With crossplay getting more and more popular, I think every game should have this option.
