I'm in the same boat. More real estate is the big win. I made a pandemic purchase of a TCL 43" 4k TV to use as a monitor primarily for programming. I sit a bit further from it: 30" rather than 24ish when working on the laptop. I drive it with a 2019 inexpensive Acer laptop running Ubuntu 20.04 and xfce. Every so often an update kills xWindows, but I can start it in safe mode and get things working.
I do find my head is on a swivel comparatively, but while noticeable without being a negative. Overall I like it. A lot. The only thing that is painful is sharing the desktop over Webex/skype. That does bog the system down and requires manual resizing of font size to inflate it so that viewers on lower resolution systems can cope with it.
