Portrait displays are worth trying, in my view. I've gone through various iterations of multi-display setups, and I've settled on having 2 x 27" portrait displays at 1440p (or scaled 4K equivalent), one directly in front of me and one to the side, plus a landscape display of any size to the other side.
Both the portrait displays get a good amount of use. The central one is most important of course but the one to the side is useful too as I don't have to turn my head much to look at it. Its usual use is documentation or similar but using it for actual work is no hardship.
The landscape display is mainly there because I work in video games, so I kind of need one. I usually use only about half of it at most, though, to avoid having to turn my head too much. If I was in some other line of work I'd probably have a 3rd portrait display instead.
(I did use the large monitor + laptop below arrangement for a while, and that was good too, but one day I knocked my drink over and it destroyed my laptop. So that prompted a rethink.)
