This is a known issue. See Add Wireguard support.
Additional it is reported that the default route is always set to the wireguard device.
Just a thought for a workaround: use wireguard without connman.
Do cp /etc/connman/main.conf /storage/.config/connman_main.conf and add ,wg to the NetworkInterfaceBlacklist line. Reboot.
Then configure wireguard using the wg command.
Use journalctl -u kodi-autostart to see error/log messages from boot.
You can try to disable the LVDS device in the kernel.
The kernel name may differ from the xorg name. Verify it with:
Remove the cardX- prefix and memorize the device name.
Edit the kernel command line:
Add video=LVDS1:d to the APPEND line (replace the found device name). Save the file and reboot.

There are rumors that option -o IPQoS=throughput is required in some ssh client/server combinations. Just try.
Well, that was it. I'm embarrassed the solution was something so trivial.
I'm afraid that stopping kodi before any changes was too automated for us to be mentioned. Fine that it's working now!
Did you stop kodi (systemctl stop kodi) before editing or deleting the userdata file?
peripherals.xml is only loaded from system directory, see xbmc/Peripherals.cpp at 18.6-Leia · xbmc/xbmc · GitHub
copied the peripherals.xml file over to the /storage/.cache/overlayfs/ov_syst directory, edited it with nano and made the changes I wanted
Unfortunately this is wrong. After mounting overlayfs simply copy/edit/delete the files in /usr/share/kodi/system.
How do I make changes to /usr/share/kodi/system/peripherals.xml or

Likely a bad card.
Not having any ATSC here in Europe recommendations are difficult.
There is no PCI Mutimedia Controller device class 0x0400 or 0x0480 visible in dmesg. Please verify with lspci.
Is the card correctly inserted in the slot?
A sleep() is never busy.
Technically now the thread is waiting at a timer event instead of waiting on an input event. I both cases no CPU time is used.
Feel free to verify the used CPU time with ps or top.
