I'm sure there is a LOT of additional information about "what you can do", but here are some very simple starting points. You can do these today if you want.
Only use Firefox with uBlock Origin installed/active for web browsing.
Use a Virtual Private Network (VPN). https://protonvpn.com is considered one of the best.
Turn off location services on your phone (this will probably be controversial but I think it makes a lot of sense).
