All IMHO naturally.

This would be a typical produced work which leaves you are lot of leeway
wrt your distribution licence.

With both 2) and 3) if you remain within the bounds of an insubstantial
your usage would be ok, even though as you correctly state both extracts
would normally be considered derivative databases and would require
release of the underlying data with the ODbL.

In both cases you are naturally free to simply produce such results on
the fly. My reading of the ODbL would seem to indicate that if you for
example geocoding on the fly you may not even have to provide an
indication from where you results were derived.
