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.

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?

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