There is curently a section for the PDDL and a general section but the
ODbL FAQ section is currently the largest part.

Right using the PDDL or ODbL + DbCL you know you've covered everything
and you don't need to worry. As it says in the FAQ entry:
Of course much of the time the the Licensor of the database is also in
the position to license the rights (if any) in the contents — the
classic example would be a database containing factual data. For this
reason we’ve created a very simple Database Contents License which you
can use in conjunction with the ODbL to ensure that you’ve licensed

Right. I think our recommendation would be that unless you really need
to think about the contents separately it is best to go with the PDDL
or ODbL+DbCL options (because they have been designed precisely for
this task of licensing database especially databases of data).
