If they were going to go really "realistic", you wouldn't even have the first or even the second officer going down on away teams, really not even any of the senior staff. You'd have dedicated teams for SAR's, geological surveys, first contact missions, etc.
I know that's not really doable for a TV show that needs to take certain dramatic licences, but I do think it would be possible to have more of a "Lower Decks" POV that would provide good storytelling fodder.
