I'm going to say one more thing about crowds/crowd calendars because I'm waiting to pick someone up and I'm bored.

In my opinion, pre-pandemic, the holy grail of
Disneyland days was a day when
Disney expected crowds that did not completely materialize. Long hours, full staffing, everything open and running at full capacity... but not actually completely packed. THOSE days were the magic. It wasn't like the parks were empty to look at, they often had a lot of people in them, but you could often hit a ton of rides/shows/experiences, and things generally ran quite smoothly.
Those days were unpredictable by nature, and anything that showed up as a "low crowd" day on a prediction calendar would definitely
NOT qualify as one of these days. The trade-off for "less people" was always less hours, less staffing, less offerings... and no actual guarantee of less people. (The past few pre-pandemic years as so many people looked at them, these calendars CREATED crowds.) The
worst days were when the parks were in "low-crowd" mode, and then "slightly more crowds" showed up and created a lot of strain.
I think both of those extremes are gone because I think reservations are here to stay. I think that now, Disney will always know how many people to plan for. On the one hand, that will help prevent the "totally overwhelmed" days that would randomly happen in February or something, but on the other, the Summer of 2019 Glory is never coming back.
