Tech moms - what online supplementary courses are you loving?

My kids are finally old enough to be engaging and following courses online. I recently came across the DOZENS of tools to learn Procreate - we’re going to pick one and try out. It’s basically mini lessons every day to learn the program. My husband already has them on “computer basics and typing” because these Gen Alpha kids only know tablets. I’m curious what other SUPPLEMENTARY (ie not math, reading, science, core curriculum) fun stuff is out there to try out? They’re too little to have other hobbies but we figured art would be a safe bet for now so that’s why we’re starting with Procreate.
