There's also the Penrose process which is theoretically useful on spinning black holes. I also watched this in the past, which has some fun ideas (that are probably a little fanciful?) [VIDEO] tl;dw: put a mirror around it and shine light in, get back lots of energy and/or blow up your whole solar system. I'm not sure if any of that would apply to a ~planet mass black hole spinning with ~planet sized angular momentum, or how solid the physics even is, but it sounds cool anyway.

Kurzgesagt had some nice summaries of: 1) Why white dwarves might be the last home for life in the universe - [LINK] 2) ...or maybe it will be black holes - [VIDEO]

Kurtzgesagt made a video explaining some possibilities. In short, you can throw mass or radiation at a spinning black hole and "steal" rotational energy from it. [VIDEO]
