It does seem nowadays that since consumers are requiring A rated products the insulation has to be thicker which includes the doors. So to maintain storage drawer and shelves space the only way you can go is to make the product deeper.
Gorenje produce a good range of refrigeration without spending an arm and a leg. They will come with a full five year warranty as well, you can see the range here
available from independant retailers. The models to look at end in DE.
Next up would be Bosch and Siemens (same stable) good quality products German design and led with a two year warranty.
Then at the top would be Miele and Liebherr. Miele are very good appliances however due to the high price of spares and gaining tech info is very slim unless you are a Miele service agent. Liebherr are at the premium end along with Miele and as far as we can tell produce some of the Miele refrigeration for them. Liebherr specialise in refrigeration so be prepared for a higher price per unit.
