Notice that I have my touchpad enabled in BIOS (my trackpoint has a faulty left button, so I'm waiting
for a replacement and currently need to use the touchpad when there is no external mouse around)

This is the output of xinput list-props when the touchpad is enabled

Could it be that our touchpads have different firmware versions? What I have is

$ journalctl --no-page -b | grep 'Touchpad model'
