Everybody else has hit the high points: good prices, less crowded, etc. and the low points: some things might be starting to shut down, shorter days, iffy weather. All I can add is that we've done several Alaska cruises in September, and they were all great. We're scheduled for another one in late September 2023, and I'm expecting to have a great time on that. Maybe rainier, but that's what rain gear is for.
