Podcasts would definitely be on that list.
You can certainly download enough of them to last a really long time, and I find that it's a less "busy" media source. It goes deeper into stories and is less "click-baity". More protein, less sugar
I'm not sure if it's accessible where you are, but Canada's public radio system has a lot of podcasts and audio books available.
You can also download a trove of old classic books at the Gutenberg project.
If you plan on visiting the library frequently, I'd also see if they provide e-books and figure out how to get them on my device. (Book books are also great, of course, but going electronic means you don't have to bring them back, so if you do not visit often, that's useful. )
(I'd also invest in several good local and regional maps. Even with cellphones, I still keep a few of those in my car because nothing beats the information density of a paper map.)
