While I won't condone piracy (there's usually better FREE software for whatever you want to accomplish anyway), it seems to me that GrapheneOS would be the BEST option for you, since it is the ONLY operating system that allows google services to run under the same restrictions (sandbox) as other user installed software. That will substantially cut down on privacy concerns since those components won't have unrestricted access to everything as they do on EVERY other option where they're installed.
PS: I do NOT use google services at all, though I do have one google application, which is indispensable. Gmaps for commuting, since it can pick the best route based on current traffic conditions. Some people will say they prefer waze, but in reality, its just a different frontend on the exact same thing since google owns it.
