Look at a 1990 Miata fitment, you'll see all of the 15" sizes listed. The 15x7.5 only comes in grey, there may be a drop-down.
All of the 7-8" ones are the C1, and the 9" model is the C3M. There is a +30mm 15x7 called the C1M as well. Keep in mind that the M-suffix versions have Miata-specific hub bores, which will be a problem for your Honda.
The wheel offset I always used on my EG Civic was 38mm. I think up to 42mm work without issue on the EF, EG, EK, and DC platforms.

I was suspicious that they were, but didn't know for sure. Thanks for clearing that up.

Although they happen to be perfect for an AW11

Unfortunately the hub bore is smaller than the typical Hondas, so no hub rings for you.
