I use nextcloud for a lot of my home data serving. It lets me have the full iCloud/Google docs experience, but with all the data on my own systems/disks. One service that is a little less known, I think, is ONLYOFFICE. It's a thick-client Word, Powerpoint, Excel, PDF-Form-making office suite. I get a ton of mileage out of it. It's honestly a bit rough around the edges and not as full-featured yet. But their mobile app works, their desktop app works, and I guess it's good enough for me. It costs like $120 once-in-a-while. That is, they do big version upgrades and expect you to pay if you want the new version. But then they do a lot of features and updates on a major version. It works out to about $120 every couple of years or so.
