I haven’t ever worked at a company where Office was the preference,

I haven't worked at an office where it wasn't. And I've done years of consulting at Deloitte, so I've seen a few places.

Many govt agencies around the world pay for Office 365 or similars. Where I work (govt health), some higher ups demand pro-level M$ office accounts. Those ain't cheap.

I suspect the vast majority of USA govt (state and federal), plus many European govts, pay a fortune for Office

Virtually every company I’ve worked at used Office primarily. And by the looks of the other comments your experience seems to be atypical.

I'd never use Google Docs for any long-form writing. I wouldn't even trust the online nature of it, not having the file stored locally.
