September section hike recommendations

Hi there, I’m considering a section hike of the PCT for 2-3 weeks starting early September. Any areas you would recommend? I’ll be flying in from the East coast so I would prioritize easy travel logistics to an airport and being around other hikers (ideally not looking for total solitude even if I just see hikers in passing).
I’ve hiked the AT, LT, and CT. I would like to do around 15 miles/day, 180-300 miles.
Thanks for any suggestions!
