Do you need Google login though? I think for every platform I have created a separate account (and don't link them together).
For example, github@mydomain.dev for github. With a password manager, I won't confused at login.
And most importantly, use fb@mydomain.dev at Facebook since I will see AD on Facebook about what I just browsed on another shopping site with the same email account.

Container is not work in this case. But I use it too, it is useful on prevent me being tracked on random website.
