I don't know why PE states that baryta papers should be considerable better than RC papers (he will properly explain)..
But as a beginners choise, just use RC papers.
They are political correct (don't curl - are easy and quick to process) and if you're using MG papers, you can place a filter in front (or back) of the lens to lower contrast.
Make a test to see about the iso. (I normally calculate around 10 iso)...
It is VERY easy - it is quick, and the results can be fascinating!
attached a couple of examples.
all from paper negatives - all RC
