I have the same issue with my MacBook Pro 16" M3 Max + Dell UE3223QE monitor+dock
Sometimes it wakes up fine by just pressing a key on the keyboard, but if I've fully turned off my monitor prior with the power switch, I can't for the life of me get the MacBook to wake up without having to open and close the lid.
The MacBook is in sleep mode, and the keyboard is turned on (indicated by the backlight of the keys being illuminated)
I never had this issue on my Intel MacBook Pro (16", 2019)
I suspect this is a security feature where accessories aren't allowed to interact with the device without prior user interaction. (You see this when you connect a USB device and MacOS asks if you want to connect this device before it actually works). I don't want to disable it though, it's a beneficial security feature... I just want to whitelist my monitor lol
