I know maybe some people on here might not like this suggestion since Google is evil and all, but if you're curious about the kinds of data Google can collect you can create a new account, use it for a day or something, then request a copy of your data at https://takeout.google.com/
I actually did this recently and compared info collected before and after I started using GrapheneOS (my previous phone was locked), and I was pleased to see they didn't have much.
