I guess most commentary questions would be off topic, since they are not technically 'sport'. But I am not sure. Are questions on sports commentary allowed?

I would say they are on-topic as a general subject; the example list of questions which are on-topic here (8 years old now, but I don't believe the consensus has significantly changed) includes "broadcasting" and two questions specifically about commentary.
Usual disclaimer here: being on-topic as a general subject does not mean that all questions about commentary are on-topic. "Who's the best soccer commentator?" is as off-topic as "Who's the best soccer player?", but that is because it's opinion based, not because it is about commentary.
