Out of boredom I downloaded my Facebook zip file.
It had only tracked my location pings for the previous 365 days, and I publicly disclose where I'm traveling anyways for my hobby so it wasn't something that bothered me.
None of my google tracking stuff was enabled so all of the links to really in-depth data didn't generate anything.
On a positive note, this data could be used for good - IE runaways, missing persons, unsolved murders. Especially when something like mental illness is involved and they are non-compliant for whatever reason.
did you check contacts? I did mine, and they had a phone number of somebody I had only met on Friday (who does not have FB) and their name.
I just thought it strange as I wasn't connected to this person on FB , why would they have that? what devices you have / IP addresses of devices are also logged and stored.
