I might have some additions:

• 8 fileserver: add Murana Cloud which you can also self-host

Some other ideas:

• Install a alternative browser and use this as your default browser for this day: Arc, Impervious, Vivaldi
• Use a proxy for your internet traffic (this is different than a VPN) more info here
• Discover and learn to use Syncthing to do backups or file sync between multiple devices
• Use a browser extension to auto redirect bigtech links to privacy-friendly alternatives
