I just had to edit a Google Doc for a university thing, and I found the mobile UI to be rather nice. The desktop UI, too, was very good, and I remember having good experiences with Google Slides before I began my privacy journey.
I am fully capable of using things like LibreOffice and ONLYOFFICE, and I currently just use Markdown and CSV for my documents and spreadsheets.
However, if there’s a FOSS and privacy respecting piece of software out there with a similar UI/UX to Google Docs/Slides/Sheets, I would would be very happy to hear about it.
Cryptpad? Or if you are up for a learning journey you could set up NextCloud and Collabora.
Nextcloud AIO will help here, although you still need to be tech savvy
etherpad kinda seemed nice, never used it much tho
For the docs part, Proton has an alternative built into Proton Drive that is directly aimed at Google Docs. I can also recommend Cryptee, which can work fully offline and is completely web-based.
