Hey there, welcome to the forum!
As far as brake work goes, I'm at about 85,000 and have not done a thing to my wheel speed sensors or parking cable. My car lived in the North East the last 5 years and ate a steady diet of salty winters with no brake issues. I've changed pads, rotors, fluid, and rear shoes on the drums without touching anything else. My car is an 8th gen but I think the brake systems are still very very similar. I've never lubed the parking brake cable, but I also haven't had an issue with it either.
Are you needing service already on your 2012? You must drive a ton. The stock front pads are generally good to about 50k I think. I swapped mine at 40 cause the rotors were "warped' from the previous owner. Changing brakes on these cars is a breeze. The only real trouble you might have is with the rotor "set" screw. There is usually one but sometimes 2 screws in the front rotor to hold it onto the hub during assembly. If you ever take the rotors off to change them don't bother putting the screws back in. They are unnecessary. Also, huge pain to remove. I ended up buying a $5 impact screwdriver from Harbor Freight. It survived the job.
