Brake pad replacement on a 2015 crossover: piston retraction and caliper bolts

[OliviaUS]

I'm planning to replace the brake pads on my 2015 crossover for the first time to save on labor costs, and I've watched several tutorials that make it seem straightforward. I have the basic tools and have done oil changes before, but I'm nervous about getting the caliper pistons retracted correctly and ensuring I don't damage the rotors. For DIYers who have tackled this job, what are the most common pitfalls for a first-timer, and is there a specific sequence or torque specification for the caliper bolts that is critical to get right for safety?
