On building a new Intel NUC 11 Enthusiast based main desktop earlier this year I installed Windows 11 Pro. I've had zero issues though there are some interface changes that I didn't like and have returned to look and behave like either Windows 10 or, in the case of the Windows Start Menu, like Windows 7 using Stardock Start 11. You can find registry hacks or simple utilities to modify any setting you aren't keen on.
Generally, if a programme/utility/app is compatible with Windows 10, it will work fine with Windows 11. I'm sure there are exceptions but I haven't come across any. Another good site for Microsoft Windows and Office is The Unity Soft.
