A1 Combo for 8yr old? What accessories and filaments should I get?

Decided on getting the A1 combo for our 8yr old’s birthday. We know literally nothing at all about 3d printing. Before I pull the trigger, is it safe, and simple enough for us to figure out together and him to take off with it without my involvement once we figure out the basics?

Also it’s very confusing what I need to get to start printing cool stuff right away. Any recs on the accessories, filaments and anything else to buy from the bambu online store?
