fillfactor: The fillfactor for a table is a percentage between 10 and 100.
100 (complete packing) is the default.

parallel_workers: If not set, the system will determine a value based on
the relation size.

I don't think including the algorithm for parallel_workers would be
appropriate for the documentation.

Hence, both are indeed "covered".
