I mean, GrapheneOS hits at least 2/3 of your demands pretty well.
The Play services are "regular" apps with permissions that you can take away.
For contacts and files you get "scopes", i.e. you decide what the app can see, while the app is left to believe that it can see everything there is.
That said, I think the marketing of GrapheneOS could be better. Every introduction of GrapheneOS I've seen paints the image of Graphene being "Absolute security, no compromises", whereas in reality GrapheneOS is the most "Things need to work, no compromises. Then make the rest as safe as possible" custom ROM that I've used thus far (in particular regarding them allowing you to install Google Play, rather than using MicroG).
