I would recommend the same. I usually only put things like Slack or documentations in the off screens - it's pretty 'read only'. I also use ultrawide screens occasionally in my hometown's house. I found the problem with 3 displays is I cannot put one application span across displays or there would be a 'bar' in the center of the application. I have to put them far left or right instead of placing them in more comfort zones.
With that being said, I ended up with 3 monitors in my apartment because I bought them incrementally across 3 years(though they're the same model). And also I play video games from time to time, for most of the games, it's better to have 3 monitors instead of an ultrawide one.
