Ok, pricing thing is scary.
1. Interesting
2. I've it installed already
3. How does vpn help?
4. Does having safari, help?
5. I use safari as default. does that work?
6. I don't use FB, Twitter. Only Youtube, Gmail
3. VPN helps by obfuscating IP address which is one way you can be tracked.
4. What you are trying to do is clear cookies and history regularly so trackers can't vacuum that data up. You can probably set similar defaults in Safari but I don't know how.
5. I advocate for Firefox because they have protections against browser's fingerprinting. I don't know if Safari has these, you would have to check.
6. You should use encrypted chat, it doesn't really matter which you choose.
