Another solution is just to fully turn off Wi-Fi and Bluetooth. (Not "disable new connections" but fully turn them off). I have a Shortcut on my iPad's homescreen that does this. Just keeping Bluetooh off definitely greatly improves idle battery life. And you can use Shortcut automations to automatically turn it back on when you take certain actions. And if you don't care about Find My at all, you can disable it deep in system settings.
This is all far from ideal.
I've been doing this with my MBA M4 since day one: I turn off Wi-Fi and Bluetooth to prevent the network and my connected keyboard and mouse from interrupting the computer's sleep.
I configured Control+Command+S as a shortcut to put the computer to sleep. While playing a music video on YouTube, I pressed the shortcut and the music stopped. However, as soon as I moved the mouse or used the keyboard, the video started playing again, even while the computer was supposedly "asleep" (with the lid open or closed).
So, at the end of the day, the best thing for me to do is turn off Wi-Fi and Bluetooth, then use the shortcut to put the device to sleep, and finally close the lid before putting the MBA in my backpack.
