I've been playing Shenzen I/O and I like the idea of Arduino/Feather but I have no idea what I would actually make if I got a microcontroller.

Home automation or LEDs are always a good start in my opinion. Home automation because it's something that will affect your life and you'll notice, LEDs because they're pretty (e.g. https://news.ycombinator.com/item?id=29468919).
