What size radial master cylinder does one need to use with standard mc28 calipers?

Anything between 16 to 19 will do just fine...

What does the different sizes do? Is it the best size to get?

Different sizes give different feel... But it's not only the bore on the radial pump that matters, but also the stroke...

For example, the bigger the stroke is, then you get more progressivity in your braking...For road use, the best combination is 19x20 (borexstroke)... If you want the pump for racing you can go 19x18 or even 19x16(extreme)...

If you'r lazy to guess sizes, just get one off a known twin rotor setup like a CBR/GSXR/R6

I have a Brembo 19x18 on my 28 and it's perfect.

A 19x18 will give you more feel and the 19x20 will give you more power.
