According to the hafas API "Frankfurt (Main) Hauptbahnhof" is the correct name. The HAFAS ID for the station is '003000010'

The names 'Frankfurt Hbf', 'F Hbf' and 'Ffm Hbf' are known as aliases by the api.

Therefore I think 'Frankfurt (Main) Hauptbahnhof' is the propper Name for the entire station.
