Well. Your user tree is fine but in your boot-user@ lizzias conf file replace xfce4-session by startxfce4.
# EDITOR=nano 66-env -e -t boot-user boot-user@ lizzias
# 66-enable -t boot-user -F boot-user@ lizzias
Your conf file should look like below in your case because you have enabled SDDM and Consolekit in your root tree. It's not a problem, you have the choice to enable them on the tree you want, but not on boot tree and they can not be enabled two times. To be clear you can not enable SDDM and Consolekit in your boot-user@ lizzias conf file and at the same time having them enabled in the root tree.

# # It also prepare the .xsession file.
# DISPLAY_MANAGER=sddm
# # Uncomment it to use a console tracker.
# # Can be any console tracker as long as the
# # corresponding frontend file exist on your system
# # e.g consolekit,elogind,...
# CONSOLE_TRACKER=consolekit
# # Create and mount the XDG_RUNTIME directory
# # at /run/user/lizzias [yes|no]
XDG_RUNTIME=!yes
# # Command to use in your .xinitrc
# # to launch your desktop e.g.: openbox-session.
# # If commented the .xinitrc file is not configured.
DESKTOP_CMDLINE=!startfxce4
After that paste the output of
# 66-intree -g
i have not yet rebooted...
Obarun# 66-intree -g
