When do you include hydronium ions in your galvanic cell diagram? And, because I've heard different things from different UAs, can we combine these ions with the reduced anions rather than writing them as two separate aqueous solutions? For example, if your cathode contained H+ and NO3-, both aqueous, could you write "HNO3(aq)" instead of "H+ (aq), NO3- (aq)"?

From what I've understood, you include it only when it's in the given equation. You can't combine ions though, just write them as given in the equations

If there are hydronium ions in your balanced redox reaction, they should be included in your cell diagram.
