I ended up with switching over to Ubuntu. I tried to get ChromeOS up and running but it wasn’t perfect.
With the AX200, wifi worked fine and the system appeared healthy for basic web browsing and the like. I didn’t encounter the Sleep problems. If I just wanted that basic functionality, I could have stopped there.
But I need Visual Studio Code, and when I installed and tried running it, it wouldn’t load completely and complained about some missing video drivers. I wasn’t able to figure out how to add them. Perhaps this is related to Debian not being a supported linux variant for Framework until Debian comes out with its next version that supports the hardware.
