As far as Windows 11 is concerned, the difference between those CPUs is hardware presence for fTPM 2.0
Windows 11 uses that for Bitlocker, Core Isolation, and (I think) Local Security Authority features.
Windows 11 is otherwise the same as 10 - I’ve yet to encounter anything that worked in 10 but didn’t in 11.
If those features aren’t important to you, you could easily perform an “unsupported” upgrade to Windows 11 and your system would be just as secure and functional as it is now. You would then be able to enable those features when you upgrade the CPU down the line.
