@dc42 That seems to have potentially done the trick! Its at least going into the print status and staying connected throughout so far.
DWC still doesn't show bed temp; will have to poke around about that as it is likely something in the macro workflows.
Edit:
Tools disappearing and temps not being set in DWC were due to some DWC settings that somehow got toggled at some point in time.
Have run several short test prints without any further disconnects now.

Yes, config.g with just M954 A1 was in /sys and the firmware file for CAN was in /firmware on previous attempts.
On this latest attempt same thing, except, I left all other files and folders in place.

Followup -> something wonky must've happened I reckon.
Backed up the newly working setup and went through and reset it back to the way Docs specify and now it works.
Same files I've used all along (copy/paste)

I won't question the gremlins in the hardware, its working now.

Same SD card; -> I did leave the other firmware binaries on the /firmware directory this time since that seemed harmless.
Its possible my adapter/reader corrupted something on previous attempts -> this time I did it through a laptop with reader built in.
