... so if the app including the SDK has permission to access location data, the SDK could be passing that location data to Facebook?

Not only could it do that, but it also totally does do that

Didn't they also use to home in information about surrounding bluetooth devices? When iOS 13 beta dropped, half of the apps suddenly asked for bluetooth permissions because Google/FB SDKs attempted to use it on app launch.

Not sure about Bluetooth devices, but the Facebook SDK definitely phones home with some system data and generates an unique identifier on first launch which is then included every further interaction the SDK has. Both of these enable fingerprinting and persistent tracking.
