Eh, not so much for Berlin. And yes, they absolutely were the masters of urban warfare - they knew what defenders could do from Stalingrad, so if they took fire from a building that wasn’t as heavily built as the Reichstag, they often brought up artillery and fired on the building over iron sights at relative point blank with heavy HE. They weren’t even trying to preserve most of Berlin for later occupation.
No, Berlin was fighting to the death. I believe Hitler was traumatized by the manner of Mussolini’s death (with his body being hung publicly in Milan), and he had some weird fear of the Soviets displaying him in a cage.
German units trying to break in to Berlin to save the city from the Soviets eventually resorted to remaining close by for as long as possible to help elements escape; their goal was to surrender to the US and British troops to the west (the Soviet payback for Axis treatment of Soviet civilians during Barbarossa was already well known).
