For educational purposes, libreoffice should be a full replacement for office. You don't need to worry about compatibility if you just decide that students and teachers will use it. Kids aren't using whatever advanced features of Excel that F500 accountants need. They just need to learn the basics of spreadsheets and e.g. what $ does when referencing a cell (something I had to teach one of my gen-z colleagues the other day anyway). They don't need VB to sync with ADP or whatever. Similarly Linux with KDE and productivity software should be fine for schools. You don't need games or the latest commercial CAD or Adobe stuff or whatever other DRM filled software unless you are in a university course for that.
