Update for this thread.
I installed Fedora 41 KDE (not a live disk, installed) on a USB stick that I am booting from. It has power profiles daemon set to balanced. I have not encountered a reboot event in a few days of sleep/wake.
A few days later, I noticed there was amd-ucode updates on arch, so I installed those, and have not experienced another reboot since (fingers crossed). My PPD is also set to balanced here.
I am now running 6.13.7-arch1-1

I have been dailying my Framework again for a few weeks now, and no reboots have happened (fingers crossed).
