I've never been totally happy with any ceramic pad I've tried including the heralded Akebono ProAct ( on my previous car) which were for me an expensive letdown. Another letdown on that same car were Bosch ceramic pads. In fact those were the only brake pads I've ever returned in my life , back to O'Reilly Auto parts.
What I can highly recommend is what I'm running on all 4 corners. They are way cheaper than OEM Mazda ceramics, have better bite and are rotor friendly (very little rotor wear) and don't dust too much more than OEM. They are a hybrid (ceramic and semi-metallic) pad that gives better stopping power and the linear feel of a semi-metallic. They also come with the stainless steel pad retaining clips that Mazda pads don't and are sold separately.
Check out these pads. Rockauto attached but Amazon should be around the same price and you may save on shipping.
For rotors, no recommendation. Maybe Powerstop you are considering. I would guess that you would not want drilled and/or slotted but would want coated rotors (at least the hub like factory) to prevent rusting. If you will be comparing prices elsewhere, be sure it's Element 3 EHT (Enhanced Hybrid Technology). The non-EHT are plain ceramic and not hybrid. Good Luck.
ETA. In the past I've had good success with the better grade of Raybestos rotors. Wagner is another brand that people seem to be satisfied with. Both companies have been in the brake business like forever.
