It always helps to start with a 'good' negative and practice to get a 'good' print from it, and go from there. If your exposure and sharpness were good to begin with, and the development was adequate for a printable neg, then all you need to do is experiment/learn what makes a good print.
Don't rush anything, and cut your sheets into strips for testing to get an idea of density and contrast. No point wasting a whole sheet when one can provide 5 tests to get the print right (exposure, contrast, etc).
Mixing paper stock is a road to confusion because it's hard enough to get to grips with a single one. Take frequent breaks, let your eyes adjust and check your tests in the light or you'll miss simple means of improving like seeing the whites aren't white or blacks are muddy.
Spend 4 nights in the darkroom now, bit of a learning curve but getting to grips with it now.
Different paper seem to have vastly different properties so that has been tough.
If shooting film makes me selection, printing is making me look even harder at what is a good shot.
