I would use Mullvad Browser for browsing as it has very strong anti-fingerprinting/tracking and Brave/Librewolf (or a different privacy Firefox fork) for anything that you need to be logged in for.

Rules for thee not for me.

Sorry for the late reply but I would follow what Privacy Guides says in this article: https://www.privacyguides.org/en/vpn/

I have ProtonVPN, but I am soon going to be switching to Mullvad as I find that they provide a better service and I like the company more.
