I only have an 11th Gen. So I can’t help you with graphics.
But I have an idea what could have caused the AX210 problem. The AX210 needs firmware which is in the firmware-iwlwifi package. This package used to belong to the non-free section but was recently moved to the non-free-firmware section. So non-free-firmware must be added to /etc/apt/sources.list. Locate the line for the sid suit and append non-free-firmware separated with a space. You should then have a line like this (propably pointing to a different mirror):
deb http://ftp.de.debian.org/debian/ sid main non-free contrib non-free-firmware
Then you can do
sudo apt update
sudo apt install firmware-iwlwifi
Hopefully wifi will work after a reboot.
