How to make android more Private?

What are everyone's recommendations on making android more private? Given Google's recent behavior around tracking and the like, I'm not really comfortable with then having all of my data. I've even contemplated going to iOS, since apple doesn't have a vested interest in me having less privacy... But I just don't like their OS lol.

I've tried GrapheneOS, and it's not awful. For usability, I did have to add Google apps back in, but at least they are sandboxes.

For the moment though, my daily driver is a Samsung S21. What can I do to make I more private?

So far, I have:

1. Switched to Samsung browser with adblock.
2. Started using duckduck go.
3. Installed duckduck go's app tracking protection. That was an eye opener.
4. Restricted location history in Google maps.

What else? I know Graphene is typically the gold standard, but I'm trying to see what I can do short of that.
