It's pretty dependent on how gentle you are with them. If you do a lot of highway driving and coast a lot to stay with the pace of traffic, your brake pads will go basically forever. If you have to deal with a lot of traffic lights and stop and go traffic in town, you'll be doing them pretty frequently.

Pads are pretty easy. I just rebuilt the rear drum brakes on my Civic back in March and that was a proper PITA. So many really strong springs that get hooked in tight places. I mean, it's only like 2 per wheel, but it felt like 8.

Is your car electric or hybrid? We're at 120k with our prius and the brakes look fantastic, since most of the time we're using magnets instead of the brake pads to stop
