A degoogled Android is still the only acceptable path, whether it is Grapheme OS or other projects like Lineage OS or /e/OS; of course, some people will harshly dismiss some of these. I don’t know if Sailfish OS is still around, postmarketOS and the different GUIs of Linux phones (Gnome/Plasma Mobile, Phosh, etc.) are great projects, but not quite stable or user-ready, in my opinion.
