Brake pads Hella Pagid or Centric

Get a set of Centric PQ (posi-quiet) pads and rotors. Way better than any of the big chain brick and mortar store offerings for less $ too

I bought that centric kit for my 18 Mazda 3 last year, no issues.

Centric Posi Quiet Ceramics & 120 Series rotors from Tire Rack. Though not a CX5, my Mazda6 is running at 60k miles on this set.

Zimmerman Cross drilled rotors from FCP Euro with Centric posi quiet ceramic pads. So much less brake dust with these pads compared to stock.

I'm running the cheapest coated rotors from rockauto and Pagid "OE" pads and I'm happy with it.

Centric OE coated "black hat" rotors and Centric posi-quiet pads are pretty damn tough to beat

I use Pagid RSL29s on my M3, I don't bother switching pads after events. They work great on the street but I'm in Texas so it rarely gets below 45 degrees here. They squeal but the dust isn't too bad. I don't daily it but I wouldn't have an issue if I did. The squeal is annoying but really not too bothersome to me even though I drive 95% of the time with my windows down.

I’ve always done centric. Good quality, good performance and good price

Centric Posi-Quiet Ceramic... I didn't like them at first, until I bedded them in one early morning and ended up warming up to them.

You'll need decent pads, and ones that can handle a car with a bit of weight behind it, think Pagid RSL29, Winmax W5 or Mintex 1166 if you're not going mad. You'll want to flush out your brake fluid and replace it with something that will take the heat as the tiny brakes on a 325i WILL overheat, its not a matter of if, its a matter of when, good fluid will stop you from boiling it and crashing!
