I would say that you should just look at 2/3" cams as cropping on the red one or others cam's doesn't makes sense or work. I would say the 2/3" scarlet but as others have said you can achieve a large DOF as long as you have enough light, though indoors (but how deep do you really need an indoor shot) might require a large amount of lights to achieve deep focus and end up turning your set into a packed sauna.
the thing is two of the camera's you mentioned do not exist so no one can tell what would look like what, the 5d as Mr Mullen said should not be cropped, so for now that leaves the red one. More realistically you should look at 2/3" broadcast camera's that are available now, perhaps an iconoscope(sp) or a si2k.
good luck and happy filming.
