If you are doing this for looks, go with what you like best. You are prob talking about loosing 8 to 12hp. On a LS1 You wouldn't notice, in a civic si it would feel like you left the emergency brake on, lol.
If you are concerned about 1/4 mile times you want the smallest tire, that still gives you traction. For me switching from 245-50-16 to 275-40-17 gave me a quiker 60ft time .04 avg improvement. But I also had a Dodge that ran a 15flat 1/4. I went to a bigger tire and my 1/4 dropped to 15.2. Since you have a Mustang I am not sure, but I would guess going to a 275-40-17 would be plenty of rubber for a stock car.

fwiw, you get the same area of contact patch, even with a wider tire... the shape of the contact patch is different though.
If you want more traction, get a better compound (stickier tire).
But to answer the question, if you want performance, get the smallest diameter widest wheels you can, as long as it clears your calipers.
18s will slow down since the mass is further from the center... think of it as rotational inertia.

Does anyone know where I can get info on how much each of the Corvette rims weigh? Or does anyone know in general? zr1, z06, c6, c5?

I guess the main thing is whether you will be carving corners or drag racing more often. The big problem with bit wheels is that they leave you with less sidewall to absorb the shock of launching, which means they spin more. An 18" rim on an f-body seems to be the breaking point as far as launching the car.
