Ask HN: Alternatives to Google suite

So as a part of trying to be more "private" online. I have started moving away from Google and Microsoft.

Currently I've moved email to Fastmail instead of gmail but am stuck on an online suite for file editing and to use DuckDuckGo for search.

My current sticking point is for online file editing (a replacement for Google Sheets/Docs/etc), an obvious choice would be office 365 but am aware that's not much better in terms of privacy than Google.

Any suggestions are appreciated.
