Do any list RF power and voltage specs?

Some do, some don't. Like anything else, some mfrs publish better data sheets than others. For example, compare Fair-Rite's data sheets with any other mfr of ferrite parts.

Nearly all list the composition of the center conductor and the shield. Most commonly available RG6sare designed for CATV/MATV, with copper clad steel center, a thin Al foil shield, and maybe a thin braid. It doesn't take much more than common sense to figure out that a thin foil shield won't handle much power, and at MF and HF will be pretty lossy. There are others with a solid copper center and a more robust braid. Belden makes an RG6 with a double copper braid shield. I found a similar cable with Pasternak's name on it in a surplus house, and grabbed it at a very good price.
