For learning materials I'd recommend Berklee on Coursera
The course on music production is not DAW-specific. When I took it (a couple of years ago) the professor was trying to build within the course a wiki comparing how to do typical tasks on different DAWs.
coursera.org/learn/technology-of-music-production
This was the course that got me started on Presonus Studio One. At the end of the course they offered a great deal to students (I bought an Audiobox interface that included S1 Artist and they gave a free upgrade to S1 Pro).
For getting started on more "industry standard" DAWs they have
coursera.org/learn/protools
coursera.org/learn/ableton-live
Note: I think it is still possible to audit the courses at no cost but it may require some clicking around
