Question 1080P 144Hz G-Sync Compatible FreeSync Display?

[ShafeDogg]

I'm currently looking for a display for the system listed below. I'm aiming for 1080P at 144Hz and I would like to be able to use G-Sync with a FreeSync display, since they are cheaper. Any suggestions? Should I go higher than 1080P@144Hz? What screen size should I go for? I was thinking of a price range no greater than $300. I haven't fully chosen storage options yet, but one will be NVMe and the other will be a 3.5" similar to those listed below. Thanks!
