Is there any documentation about the hierarchy of header files and
when to use which one?

I've been bitten by using only Eigen/Core but using Random.
That's hard for a beginner!

yes this is documented every where in the doc. You have one header per module. For each function/class which are not in the Core module the documentation recalls you what is its respective module and which header has to be included. You also have one documentation page per module which explain what does the module contains. The tutorial also warns when a function is in the Array module. Honestly, I don't know what to do in addition to all these warnings!

OK, and what is if I need functionality from several headers.
Just include them all?

Thanks for being patient!

yes, but of course since Array depends on Core including Array automatically include Core, etc.
