>The only way I can really pass them on is if I walk to the “little free library” thing in a nearby park and donate them there

You could also post them to a local free giveaway group if you're online, say on Facebook or somewhere. A "Buy Nothing" group for your area would be a great start. You can just do a no-contact "porch pickup" if you wanted.

Separately, I think the Kindle would be a great choice for you, with a card to your local library, and some other libraries that people have suggested on this page, you could be in great shape through Libby.
