A 15 inch wheel keeps the tall sidewall a Miata, an EG or EK Civic or an older Integra was built around, and it is the size where the light wheel plus a 195 or 205 tire makes the car feel quickest. Tire choice is the trade off, because the performance lines thin out under 16 inches. The brake caliper behind the wheel sets the smallest diameter a car takes. What is left over is sidewall, and sidewall is what soaks up a pothole.
179 designs on this site come in 15 inch, in 10 widths from 4 to 10 inches wide. 15x8 has the most designs (106), then 15x7 (75). The bolt patterns with the most 15 inch designs are 4x100, 5x114.3 and 5x100. Diameter is the easy part. Width and offset are what rub, so pick your car and the page keeps only the 15 inch sets that clear the brakes and fenders, with the aggressive stance option if you want the wheel out at the fender.
