Same, I switched back to a single 27" screen last year. For me it's better to focus on one thing at a time especially since my eyes aren't the best, and I switch between virtual desktops with F1-F4 (or when I use my mac with the 3-finger swipe gesture).
MacOS also has ctrl+left/right for switching virtual desktops. The gesture can get a bit tedious if you're jumping across multiple desktops in one go. I don't think it's particularly ergonomic either.
