There is no wrong answer, but there may be a right answer for you! What do you like? What needs do you have?
We are pretty fit and active, so questions of "what is it close to" didn't matter to us, we knew we'd be close to some things and farther from others and be walking plenty either way.
But my BIL, who traveled with us in a connecting stateroom, is a very light sleeper, so being surrounded by other cabins and not common areas made sense to us, but if we had gotten loud neighbors, it might have backfired on us.
On our trip, a Veranda was only about 10% more than an inside, so we went for that. And since we were doing that, and knew we'd spend a bunch of time in our cabin, we wanted to go fairly high up, for the view.
Think about the people in your group, and your budget. Keep in mind that not only do inside/outside/veranda have different prices, sometimes forward/aft/middle or various decks have different prices, so you might have preferences, but then you have to decide, "do I want to pay extra for THAT?"
