The Windows 11 LTSC version just leaked on Chinese forums. I wouldn't use that ISO but would wait for the official release. Seems like the "best" version of Windows.

Use Chris Titus' WinUtil on a normal install: https://github.com/ChrisTitusTech/winutil. He has put a lot of effort into this tool and it works great.
If you want to go full try-hard you can do it yourself. Buy NTLite and go to town on stripping stuff out. You'll probably break something but it is fun to play with.
