Get a NAS with #Docker support (like #TrueNAS. You can install web-services like @nextcloud which is a completely self hostable Google Drive/Google Docs replacement with addons to extend functionality.

#DuckDuckGo is currently the best search engine that isn't self hosted however #SearXNG is self hostable and very customisable.

#OSMAnd (customisable) or #OrganicMaps (straight forward) for Maps. Both use #OpenStreetMaps

#Android replacement, well Android. I personally recommend @calyxos which comes with an open source replacement to emulate Play Services called #MicroG

Although #Proton is technically a great service, CEO has come out as a Trump supporter so I'll leave that to your personal opinon. Another good service is @Tutanota
