I pay a lot of attention to what goes in my profile. My wife and I are older so several of our friends have serious health issues. We are careful to use Tor or private browsing with DuckDuckGo when doing medical related web searches. I also switched over to G Suite for $10/month in the hope that I am not being ‘harvested’ as much as when I used to use Google’s services for free. I cringe when I see the private data young relatives leak on FB.
EDIT: and, of course, keep location tracking turned off.

I shutter to think what conclusions the AI overlords draw from my tracking data showing me going to a methadone clinic multiple times a day as part of my work -- probably think I'm the most strung-out human in history.
I try to turn off tracking but we all know how that goes...
If you're already a paying data subject consider ProtonMail with ProtonVPN. For example, ProtonVPN has a built in Tor mode. Works quite well for me - I can recommend.
