What features should I prioritize when buying a new refrigerator for a small kitchen?

I'm in the market for a new refrigerator and my kitchen space is quite limited. I want to make sure I choose one that maximizes usability without compromising on essential features. I've seen models ranging from compact designs to those with innovative storage solutions.

What should I prioritize? Is energy efficiency more important than features like adjustable shelves or a water dispenser?

I'd love to hear your experiences and any recommendations for brands that excel in small spaces.
