pve-no-subscription is 5.13.19-4 and pvetest is 5.13.19-5. Both fixed the startup delay and reboot/shutdown freezes. Thanks alot for all your time and assistance!
Removing the card doesn't stop the delays or hanging on restarts but I noticed this in the journal around the time of the delay:
Mar 02 18:32:19 pve02 systemd[1]: Starting Load/Save Screen Backlight Brightness of backlight:acpi_video0...
Mar 02 18:32:19 pve02 systemd[1]: Finished Load/Save...
Sorry about that. It was one of the first things I looked at but forgot to mention.
Here the full dmesg. The delay happens after the 15 second mark.

This is the partial shutdown log. The full log is also available at the same pastebin link.

Thanks for the quick reply. No, it's a Minisforum HM80. Your post got me thinking. I booted a Debian live CD and it showed the same behavior. I then installed Debian 11.2 and maunally installed the Intel firmware but there was no change. I installed Windows 10 and the wifi and bt adapters...
