To add to what Forester1 is saying, some newer software now requires that TPM be enabled and operational. You may be able to get away with Windows 10 if none of your software will require any updates, but you know as well as I that as time goes on an update will be necessary requiring you to upgrade to Windows 11, or some other future version anyway.
The other issue you are going to run into in the future is drivers for printers and your video card, or sound card for instance. You may be able to use the current Windows 10 drivers now but eventually your video card will no longer receive updated drivers for Windows 10 and the drivers for Windows 11 will receive needed bug fixes and features.
As I said, I have two systems that run Windows 10. They are both older hardware and run proprietary software with one of them running a program that cannot run on Windows 11 due to how it works. I also have three machines running Windows 11. They all run fine and two of them are higher end hardware that have TRS-Plus installed. The performance is much better than it was with Windows 10 because drivers are optimized for Windows 11 and the OS supports gaming quite well.
While many of us here do not like Windows 11, there are ways to turn off most of the annoyances. After turning these off, it works pretty well and is mostly like Windows 10 with a different interface. In case you are wondering, I am among those that don't like Windows 11 mostly because of the stupid childish things that are included and the in-your-face-bling that Windows 11 has. Tuning down those makes the OS better still.
