(real quick, I should note that superman is so overpowered that he admits he has to constantly keep himself in check to make sure he doesn't break anyone too badly. he likened it to "living in a world of cardboard." that's all I have to say.)

That’s a constant issue he has, and his only real weakness.  Kryptonite, depending on the writer, doesn’t hurt Superman, it just drains his solar powered plant battery.  He doesn’t resist magic, but it doesn’t stop him.

Superman’s only real weakness is that he holds back.  That’s it.  He’s limitless, but limits himself to keep from breaking everything or solving everyone’s problems.

For an example of Superman not holding back, see Robin with superpowers in Teen Titans GO! (Why DC?  WHY?!?)
