I think that the capacitance grows continuously with the increase of the
outer radius of the terminal, no matter what it its shape.  The actual
area of the terminal has little influence on the capacitance. The maximum
distance from the center is the main factor. A sphere has the maximum
capacitance, 111 pF per meter of radius. A toroid somewhat less, but not
much. A "rectanguloid" would have less capacitance than a toroid with
the same outer diameter, but not much less.
