I tried to dip into the material as much as possible, I was surprised to find out that there are many good podcasts about the field of SFF. I really like The Writer and the Critic podcast and The Coode Street Podcast. The discussions are remarkably thoughtful and well informed. I picked the episodes from the last few years that discussed books and stories that I had actually read, but I don't think I read enough to be interested in every show.
There is a podcast about the mechanics of writing which seemed very good called Writing Excuses, by Brandon Sanderson, Mary Robinette Kowal, and others. As a reader, not a writer, I find it interesting to hear about how writers perform their craft because it lets me understand why some stories work or don't work.
