MSI Optix G241 has legendary at this point Panda Panel, with wide color gamut coverage, and pretty decent response times.
Depending on the testing methodology, reviewers suggest that response time is decent enough to give 92% of transitions within the "required+1ms" transition window, for a true 144 Hz refresh rate.
Only OLED panels have 1 ms response times, even the best IPS panels, the LG's Nano IPS panels do not have 1 ms without incredible amount of overshoot(inverse ghosting).
I do not know where you live, but the monitors to be interested in for FPS games: AOC 24G2U, MSI Optix G241, Acer Nitro XV242YP, Acer Nitro XF243Y - those are 144 Hz/165 Hz monitors with 23.8 inch panels, but from Panda and Innolux, respectively. Those Acer monitors have Innolux panel with insane response times. Here is the review of XF243Y:

Here are reviews for AOC 24G2U:

For 24.5 inch IPS, 1080p, 144 Hz monitors there is effectively one to consider:
BenQ EX2510, with 249$ MSRP.
Here are reviews for it:

From 240 Hz monitors there will be plenty of 240 Hz IPS displays this upcoming year, and the trend that we can see is that 1080p, IPS, 240 Hz is the new 165 Hz fro the same price category

.
I won't spoil everything but first glimpses suggest that is the case: Lenovo Legion Y25-25 has been price cut on MSRP to 319$ from 349$, and can be get for 239$ on promotions, Asus VG259QM, which is regarded as best 240 Hz 25 inch IPS monitor has been... discontinued, and replaced by VG259QMY model which has exactly the same specs as VG259QM, but has lower MSRP price tag: 319$ the same as Legion Y25-25.
If you talk about the difference between refresh rate and FPS this is a very good, and informative video about the topic:
Even if you have 60 Hz panel, but you still do not limit the framerate, and allow your GPU to run at full tilt, you still; get the benefits, of having the higher refresh rate, and lower input lag, than if you would have with 60/60 Hz refresh rate and FPS.
