I have a hamster heaven so I can't comment on the Plaza but what I would say is good for a nervous hamster is a the large front door. Really helped me bond with Robin, a nervous little Syrian. I had him in my tank to start with but he really didn't like the hand from above or space above him but he's done much better having a cage with a large front door he can come up to but that I can also easily access the things in his cage too. So the large door is the main thing I'd look for on future cages.
