When I first de-googled my android device, I came across the FSFE. They are running a campaign to free your android and regain control. I’m sure you may have come across it. They recommend ReplicantOS and LineageOS on their site but I think /e/ would be another good addition. Is it possible for someone to make contact to see if it is possible to update their webpage with this project? It might have brought me here quicker!!
Let’s wait till /e/ changed the name and then list /e/ on all kind of alternatives pages.
My favorite is privacytools.io
