There is a button below those resolutions that says "Show All Resolutions". I buy the app BetterDisplay for my M1 14" MacBook Pro because it allows me to use up to 1600 nit brightness full time and in between Apple's brightness. I use it on a cheapie 32" display with a M2 Mac mini and it makes it look much better. Not sure if it will give you what you are looking for but, it might be worth a try. You can try before you buy.
