LIke David said, you need rise for movements, and probably a decent amount of your work will be vertical....that leads me to suggest a Super Graphic with a rotating back. The only drawback is that it doesn't handle lenses below 100mm well as it doesn't have focusable rails inside the bed. I have used a 65mm in a helical mount with a Super with good results.
In the city, even if you don't think of your project as "doing architecturals," the architecture is part of the environment and often forms part of the composition, so if you have rise and shift, you'll probably use it.
i probably would do some architecture stuff, but for the most part i would need close focusing, not rangefinder infinity focusing with a high f-stop. i usually try to shoot 1/60 (or faster) and my fstop range is usually between 2.8-11
For your needs I recommend a baby speed or crown with a roll film back, 6X9 back which shoot 8 frames to start. Lighter and easier to handhold or use with a monopod, less expensive in case you do get jacked. If the bady speed works out then consider a 4X5 press camera.
