Considering a used BZ4x, prioritize a CPO warranty y/n?

I'm interested in a used BZ4x for my first EV as a daily work commuter that'll charge in the garage every night.

Most of the ones available in my area and budget are trade-ins at non-Toyota dealers. Which is to say, no warranty, correct?

I understand AC compressor failure is common. Do I need a CPO warranty from Toyota for this to be a free service at a dealer, or has this problem reached recall status and is free for all owners regardless of purchase place?

Are there any other common problems that would make a CPO warranty from a Toyota dealer particularly wise, or is the AC compressor the only gotcha?

Thanks!
