Go with Tracking Control, in the same post @egx470 has quoted me I explain how the IP is barely used for tracking. I also explain some real uses for VPNs.
You can also check these articles that explain a little more on the subject, explaining on greater length what a VPN really is and what it is not: (the first article also includes a tool for telling if you really need a VPN, the second article, that is also linked on the first, goes a little more on the technical details of VPNs without being really technical so anyone can understand)
The cons of using a Tracker Control software is that on Android it uses your battery. It could also potentially break something, but I don’t remember ever seeing that, it’s more theoretical than really true, since for stuff to break because of your tracker control they must be bad developed.
The pros of Tracker Control is that all the BigTech will track you a ton less. Sometimes I see someone commenting “but you can fingerprint when you see someone blocking fingerprinting”. And while that’s true, this is something only the BigTech has resources and willing to do.
Because if you block Google Analytics from a news site, Google won’t know you accessed it because you never connected to their servers from this site. The news site barely put efforts on that stuff they call a news article, let alone they’ll put any into building or implementing a system to detect and track someone who’s blocking trackers to then report to Google. They just want to slap some external libraries to check how to improve their site and some to deliver ads to collect money and the maximum they’ll do is limit your access because you blocked the ads.
So the “but you can fingerprint when you see someone blocking fingerprinting” only happens when you access Google, Facebook, Microsoft, Twitter and other BigTech directly. Tracking to such extent is only an advantage for them, the small site won’t gain anything.
On the same screen you can disable “Background data” you can also disable internet access completely or limit to WiFi, etc. Some apps have internet access just to phone home or for features you’ll never use, disabling is the safest route.
