From: Eindhoven, the Netherlands
Larry, very interesting question.
In western Europe, during the 40+ years since WW2, the landscape there has seen major changes with respect to major roads (highways, national roads) and urban areas: major roads have, to a large extent, been moved out of the cities, reducing the importance of seizing urban areas.
For example, (since I've been living in that region), an operation 'Market Garden' in 1989 would not have fight through the cities of Eindhoven, Nijmegen or Arnhem in order to seize the main road and bridges towards and across the Rhine as they did in 1944.
Instead, the 1989 'Hell's Highway' of N2, N50, A50, would by-pass Eindhoven to the west, 's Hertogenbosch to the south, and both Nijmegen and Arnhem to the west to cross the Rhine at Oosterbeek. (The 2019 'Hell's Highway' would match the 'original' trajectory again, but still bypass the cities and larger villages, thanks to a new A50 highway connecting Eindhoven and Nijmegen).
In such a scenario, large cities still would be to able to hide strong forces, but these forces might have to attack out from the city instead of defend the city itself.
