My philosophy is that there is a point of diminishing returns and complete 100% tracking-free web activity is painful/impossible. But I do think you can get 95% there with minimal sacrifices. None of this is foolproof 100%, but it definitely throws sand into the gears of the trackers:
Browser - Firefox with NoScypt and Adblock
Search Engine - Duckduckgo, you can still be tracked in some ways though
Email - Unfortunately I still use Gmail, but I hear good things about Proton mail. I really need to switch, laziness has more to do with this than anything.
What type of phone you have - Apple is the only large/mainstream company that is committed to privacy in the smartphone market. Any of their phones are equal on privacy grounds. If you are concerned with law enforcement, biometrics are a gray area on needing a warrant. So for instance, the new face ID, they could hold up your phone to your face, and that may be enough for them to search your phone. If you had fingerprint or passcode, they cannot force you to unlock your phone for them. So just know Face ID is a gray area right now. I exclusively buy Apple now largely for their privacy respecting stance, I use their cloud service, their photo management apps, etc... Google it seems is caring less and less about privacy as time goes on.
Map app - Google maps tracks you but is far ahead of any other map apps. Apple has made some recent improvements with iOS 12, but I haven't used it enough to judge how good it is. I tried and wanted so hard to replace Google maps with Apple maps for privacy reasons and it was just so bad that I couldn't. We'll see how that changes.
VPN services - I use NordVPN. I would love second opinions on VPN services, but I have had negative experiences with this. The problem is that many companies, Amazon, Hulu, etc... get the IP addresses of the VPN servers and blacklist them. So the VPN service itself is fine, but you end up having to turn on/off the VPN service so often that it just becomes more trouble than it's worth. Tor is painfully slow and worthless as well. I would love a better solution on this.
There's a good book called 'The Inevitable' that talks about inevitable technological trends that are only a matter of time. One of the topics is that privacy eventually becoming a thing of the past. With all the cameras out there, you will be tracked whether or not you agree to it, so doing the above may only be effective for a few years, and then only partially effective after that.
