Gosh… 
that’s depressing.
I mean I recently switched to a de-googled phone and it’s a pain in the neck half of the time, but in the end I still need some commercial apps to go about my life, banking apps, transport and delivery applications, some commercial messaging app like Line App. Tracker Control does catch a bit. But some of these apps just run on android.client.google.com and won’t work if blocked. Then there’s the browser finger printing and I am not even sure of how much data Duck Duck Go browser (which I chose) is able to block. Even then fingerprinting can help build a profile and that can’t be blocked (perhaps only spoofed). Then there’s all the logins (I’m using email aliasing everywhere to avoid linking accounts hoping it has some impact).
But then I wonder: is it really efficient? Is all the trouble worth the results? I’m not verse enough to even understand everything and need to take your word on it. Maybe in the end I’ll be caught by Google and the Zuck machine. So sometimes i ask myself why don’t I give in and install stock android and enjoy the pros?
