Light Manipulation And Dark Manipulation (assuming I completely mastered them both) if i'm being selfish then I can do many things with those powers, like altering space and time with darkness, control shadows, creating blackholes with it and storing things through dimensions with it and empower myself with darkness While I can cause a big bang with light, move at the speed of light, shoot lasers of death, use rainbow light with symbolic connections (like blue means cold, freezing things with it or red means hot, making it burn through things easier for example), travelling through space, manipulate colours and reflections as they exists because of light and empowering myself with light (with Both of the empowerment from both, I can make myself both stronger physically, mentally (maybe) and ability-wise when I'm near light or darkness) I can make myself intangible by turning into either light or darkness and even combining both powers into twilight, making me even stronger and many more.

Selfless/good: I would use light to purify people (light represents pureness and good in some ways) and darkness to absorb their corruption away from them (darkness represents evil in some way but darkness is known to absorb things and of course I know alignment with both of the powers depends on the users) which would eventually lead to world peace (of just go planetary scale which would induce world peace much easier and end wars), heal people from wounds and illnesses with either light or darknesss and many more. I would go the good/selfless way even though it's more boring :p
