Use LTSC. It'll fix all the issues you are mentioning here.

AFAIK Office isn't supported on LTSC fka. LTSB.

Installed LTSB for a conservative superior. He just wanted to work, without changes. I supported that happily. Until we had to start using Office 365.

Or did they revert that restriction?

Second ltsc -look into it once you try you will never go back. Available from various resellers nowadays. It is, what windows should be sold as.

LTSC cannot be bought as a regular customer unfortunately. Legally, regular customers are only allowed to use the enshittified version.
