I isolate containers by the type of account I am using on there.
So FB gets a different container. Google accounts get a container each. When I need to log in with Google - use the Google account's container.
Work gets different ones - depending on nature of work.
That makes it easy to manage containers for me.
In theory that account's data tracking to an extent is limited. But with browser fingerprinting I doubt this whole set up is very useful once you start aggregating data from multiple providers.
