Personally, I'm not a fan of podcasts at all. I've tried, and listened to some interesting ones, but in the end I'd much rather consume the same content by reading instead of listening. It's faster, it's easier to skim and skip around, you can have hyperlinks to other references, etc. Overall, text just works better for the kinds of content I'm interested in. There's a podcast related to a product I work with that I'…
My counterargument to that is that in order to do any of those things you need to have your eyes engaged with the content. I can listen to podcasts (or audiobooks) while at the gym, cooking, doing laundry, cleaning dishes, or going to pick my kid from school. That means to me more than the advantages you mentioned.
One additional advantage: getting to sleep. I don't enjoy sleeping. If i have a light source near me, be it a lamp or a screen, I don't feel sleepy at all. I can't fall asleep while watching a Netflix show that I like. I have done the experiment. I can feel sleepy while reading a book, but an engaging one and a night lamp will keep me awake: I read the first Harry Potter volume in a single sleep-less night. Listening to podcasts with the lights off and my eyes closed makes me drift to sleep much more easily.
