You'll always be exposed to some degree online. That's the unfortunate truth of the web today. There are things that you can mitigate your exposure.
You probably are a lot further along this path than you already think.
Things I Do
- Use DuckDuckGo or another privacy-focused search engine
- Kagi is an interesting alternative that I'm exploring
- Use a third-party email client (like Apple Mail or similar)
- I really like Mimestream on the Mac for Gmail
- I want to switch to Proton Mail instead of Gmail as my email service but haven't made the jump yet
- Use a physical 2FA key
- Personally I like Yubikey
- Get two and set up both at the same time, you'll thank me later
- Use a robust ad blocker
- Something like 1Blocker for Safari is fantastic
- Also provides a VPN configuration for your phone that blocks in-app trackers
- I use uBlock Origin on Firefox
- Something like 1Blocker for Safari is fantastic
- Use a password manager
- Delete Facebook
- Or at least just use the mobile site in its own browser to prevent cross-site tracking
- I technically have Facebook for my Oculus Quest 2, but I don't have it signed in anywhere except for the Oculus
- Set up OpenVPN on your home network to allow you to VPN into your personal network on sketchy WiFi
