I'm noting that with the Raspbian Buster Lite + xserver-xorg + nodm minimalistic installation, you're missing the xset command which is useful for adjusting things like turning off the Energy Start features.
sudo apt-get install x11-xserver-utils
xset s off
xset -dpms
xset s noblank
This might possibly be useful but then again, maybe it's not an issue. (I'm currently troubleshooting a reboot issue on a Pi4B with a display which sleeps every reboot cycle in such a way that the Pi won't continue without user intervention on the display's power button.)
