Definitely do not compare 2022 to this year, travel last year was super covid-y since everyone started traveling much much more than 2020 and 2021, this year has already been lighter. 2022 was off the charts in crowds with the revenge travel (I hate that term), and crowd predictions that were way off because of it. We do have to face facts that for the most part, Disney is always crowded now but there are times it will be less so and September of this year is one of them. I just don't think the disney with super low crowds really exists anymore. But, the earlier in September you can go, the better as that's going to be less crowded and as you get closer to Oct, crowds will tick up.
We've been several times this year and last year and this year's crowds, overall, (not picking out oddball peak travel dates), have been less. We went spring break 2022 and compared to this year, 2022 was much, much more crowded. Same for our summer visit, we went the first week of Aug last year, compared to this year, it was noticeably less guests this past month. Are parks empty? Definitely not, but are these trips enjoyable? Absolutely! Our trip a few week's back was great. If anyone's goal is to avoid crowds completely, then they need not visit WDW.
Also, keep in mind that super crowded feeling parks can still have manageable wait times and not as crowded parks can have really crazy high wait times. This is due to park absorption rates (guests to ride/attraction ratios), G+ LL and ride closures. Don't let crowd calendars and open travel scare you off.
