Pretty sure you’re getting downvoted because people hate Brave and you seem to have put it at the top of your list. People hate the company and founder (with good reason) and the scammy crypto aspect. However, the browser consistently gets top tier ratings on it’s privacy implementation (from a technical perspective). I personally have mixed feelings about it. If you MUST use a chromium based browser (and sometimes I must) Brave is an obvious choice (again, from a technical perspective).

Add cromite (the main bromite fork) which is on Windows and Android, and Mull by DivestOS (like arkenfox for Android). If you want to make a mobile section I would recommend Mull, Cromite, Fenix (fdroid). The thing with privacy browsers is they differ from security centric browsers. Vandium and Mulch are chromium security browsers for Graphene and Divest respectively, Cromite is a privacy chromium browser with good security as well. Ungoogled is designed as a drop in replacement for vanilla Chromium, and has custom flags for hardenning that must be enabled manually.
