I assume "official stock OEM Android" is what you meant, and I hope you'll give specifics of the things you mention. Alternative browsers like ungoogled-chromium-android, Cromite, Vanadium, and some others purport to have stripped most of that out from the Chromium browser, while GrapheneOS, LineageOS, /e/OS, and maybe some others purport to do that at the OS level.

What do you mean?
