I just know that Steinberg states here that the free HSSE does not contain any content:
True or false?

The free HALion Sonic SE download version does not contain any content.
I you want to try HSSE out, why not get the Cubase Elements Trial version (linked in a post above)? I suppose all content for HSSE is in that trial so you can try both HSSE and Cubase Elements in one go.
