Spend like 5-15 minutes in the practice range when you get on every day. Practice tracking targets as you move around them, straifing while shooting the targets all the way in the back of the range, quickly snapshooting between targets. Don't just stand there still and call it a day when you land shots, you and your enemies are almost never still, and so practice any way you can in which you or the target or moving.

Woohoojin made some training videos for Valorant. Go watch those and implement some of those training tips also. Obviously, very different games, but aim is aim.

Check what your sensitivity is also. If you've never thought about it, you're most likely running far higher than recommended. Moving your mouse from one side of your active space to the other should be around one full rotation in game. Yes, it will feel slow. Mine is more like one and a half turns because I have a lot of space. Lowering your sens won't hinder you as much as you think in CQB, and will help tremendously with range.
