I can't recommend any specifics for 4K, but here are some ones that popped up on Newegg, first 2 shipped from USA and 3rd from Ireland...
One has 1ms reponse (apparently when not using Freesync which I'm unsure how PS5 games will support), otherwise 5ms for the rest.
Site lets you filter by alot of factors (seems slightly different filters in "gaming monitor" section VS just "4k monitors" although content overlaps)
