[Moto G7 Power ROMs, Kernels, Recoveries, & Other D] jkeuclid:
alright thanks for this, I'm downloading the fw now, but I was already booted into the .img file so I wiped all partitions and tried to boot into slot A but there is no OS installed which I about figured anyhow so will flash once downloaded, hopefully I can finally get going here. I really appreciate the input and will update accordingly.

Update: seemed to flash successfully (followed instructions in OP here), rebooted normally to OS, here's the flash dialogue:

I installed Magisk Manager while in the OS but didn't install Magsik itself, here's a ss:

Went back to fastboot install Magisk, seemed to install fine but rebooted back to recovery and now touch no longer works, perhaps a reflash of stock? boy oh boy this is a challenge...

reflashed fw, now back to sq1
