> Suspend will sap 30% of my energy by morning, even in "deep" sleep, and the computer won't wake properly
That's just unacceptable: without wake timers (so outside "connected standby"), S0ix on a Intel 11th or 12th gen should use at most 0.7% of the battery per hour, so 7% over 10h (assuming you like long nights!). A well configured system should aim for about half as much, so between 3 and 4% over 10h.
You are getting about 5x worse power consumption during sleep than a normal modern system, and 10x worse than a well configured system.
