I think some of the best purchases I've made for my kids' development is Apple TV and YouTube Premium ($13/month for no ads is a great deal). My 4yo got into math heavily for a while, and shows like NumberBlocks were a big part of that. He got into drumming this last year, and there's so much great content from kids not much older than him showing how to play pretty much any song you like. That really motivated him. Any time we have a question pop-up that is best visualized to explain, like "Where does the poop go when we flush?", or "How does the wheat for bread grow?" - we just pick up the remote, ask the question with voice, and there's usually a couple of good quality clips to choose from. Yes, there's a ton of junk. Don't let kids mindless watching YouTube (or yourself - I'm often guilty when the insomnia kicks in). But its also a total game-changer for the breadth of on-demand quality educational content if you use it right.
