If you need a Chromium derivative, then Brave is probably the best choice. It's open-source, and includes ad blocking. Just don't use its crypto token.
I prefer Firefox over Brave, but sometimes I might need a Chromium derivative for a particular site.
And a service like SimpleLogin for having a different email address per service.
And unless you're using a social network site and you want your followers from other social network to find you there, use a different username too.
