BASIC CROSSHAIR COMMANDS:
alters crosshair size ➨ cl_crosshairsize [x]
alters crosshair color ➨ cl_crosshaircolor [x]
alters crosshair opacity ➨ cl_crosshairalpha [x]
alters crosshair thickness ➨ cl_crosshairthickness [x]
alters crosshair gap when shooting ➨ cl_dynamiccrosshair [x]
alters crosshair gap when using different weapon ➨ cl_crosshairspreadscale [x]


NOTE:
To remove moving gap when shooting:
➨ cl_dynamiccrosshair 0


Commands that changes nothing for me so i just put 0 for them:
➨ cl_legacy_crosshair_scale 0
➨ cl_crosshairscale 0


Important commands that gets you small & static crosshair gap:

It changes values from 0 to ∞, but its only a matter of values before you cant even see your crosshair anymore.


cl_crosshairspreadscale changes your crosshair gap with values between 0 to 1.
➨ cl_crosshairspreadscale 0.00-0.05: gets you a nice -4 gap like in csgo
➨ cl_crosshairspreadscale 0.06-1.00: starting to change the gap with different weapons


NOTE:
➨ Unfortunately I can only find a way to get it to -4 gap like in csgo. Not possible to get a static crosshair gap with -3, -2, -1... gap like in csgo as far as Im concerned.
➨ To get a small & static crosshair gap with all weapons,

UPDATE 21/4/2025:
➨ Found -3 gap from csgo
➨ To get gap -4 : cl_crosshairspreadscale 0.01
➨ To get gap -3 : cl_crosshairspreadscale 0.1

Im using 1920x1080 native res for the command, update me if stretched res have different gap
