That is what you believe. I cannot talk much for actual MS Word or LibreOffice (WP) because I do not really use a Word Processor (last MS Word I ran was 30 years ago ?).
But, that “MS Word” is really full of (hidden) features…
And, even in today’s macOS, I discover every week something new that I do not suspect was already in the OS (add a prefix to one or many files in the Finder to cite my last discovery).
At your place (I am not), I would list what features I need and ask around me about a MS Word (or other) specialist if these features exists and where. Then, I would create a tutorial and train my users.
As I wrote above, I am not at your place and you know far better what you want / need.
This is just a clue (and yes, sometimes I follow my own clues )
