Good advice except the gmail account.  Google also tracks your machine id and that's even more valuable than your IP since we all hide behind a VPN these days.  I encourage you to look into proton mail.  They've been awesome!! I always use my VPN I never surf the net on my cell because I can't fully wipe my history like I can on my laptop. (I use Glary Utilities to keep her out of the box clean) I even keep my cellphone in a Faraday pouch when I'm on the move.  (I live in Texas and we drive fast or we get run over) It's really hard to get away from these pricks but I try to control what they know as much as possible.  Hopefully a white-hat hacker will see this and tell me the myriad of things I'm overlooking and help me take control back.
