When you'd hear it
-군요 is polite and common when reacting to something just noticed, especially in conversation and dramas. -구나 is intimate or used in self-talk, while -구먼 sounds old-fashioned or literary and is often associated with older speakers or written dialogue.
What learners get wrong
Learners often treat -군요 as interchangeable with -네요. Both can express a reaction, but -군요 more clearly presents the information as a newly realized fact, while -네요 often highlights an immediate impression.
