You don't have to wait to close the lid, you can close it right away, but anyway, why close the lid? I don't normally do that if it's sitting on a desk. As for shutting down every night on laptops, people that use a desktop too, or came from a desktop, they do tend to do a full shutdown every night. And desktop users, a lot of them do even though I tell them not to. Enough hardware has trouble with sleep states, especially USB connected hardware -- even on the M1, that it's not such a bad thing to just do a shutdown rather than discovering something didn't come out of sleep right. My USB Nic sometimes doesn't wake up properly on my MBA.
The USB sleep issues are definitely a problem and Apple should fix them. I can also understand that folks using desktops tend to turn them off more frequently. To clarify: I definitely have nothing agains improving the performance of application launches after cold boot, I just disagree that this issue ranks as high on the severity list as some in this thread appear to suggest.
Does anyone know how is it on Monterey? If Apple intended to change the behavior, they would have done it on macOS 12. If there are no changes in regards to cold app launch there, then I wouldn't get my hopes up.
