Here's my take. None of the intended uses will get the brakes really hot but will see frequent application cold. By that I mean relative to road racing/ road courses hot. Therefore the trick will be to match the initial bite of the fronts with the EBC reds. Initial application is when the drums will do the most critical work, then the weight starts shifting forward.
That said, as a class, I still lean toward the semi-metallics as they've always felt better in my personal experience, and in general will tolerate higher temps better than organics.
Reality is you will have to do some experimentation.
If you're looking at off the shelf (parts store) shoes, there's a thread discussing
Brake Lining Edge Codes. If you can find he edge codes from an original set used on the e-bodies, that would be a benchmark baseline.
Porterfield has several choices for shoes. I'm using their RS4 (street compound) on both the front pads and rear shoes. They also will arc the linings if you give them the drum diameter.
Another place is Rochester Brake and Clutch. Tom Quad uses them for his track cars but they seem to have pretty wide selection but you pretty much have to call them.
IIRC, Firmfeel has 'carbon metallic' brand linings for shoes that are also appropriate for street type brake temperatures.
