By inspecting journalctl logs I found the lightdm service was not dying gracefully on sudo reboot (which I believe first sends a sigterm) and then dying ungracefully still after later receiving a sigkill. This info was not in /var/log/syslog.
gaveThen my SDRAM bricked, AKA my pi died and would power up but not boot, showing a solid red light and 8 short flashes of green. I got an identical pi, put the sd card in, and everything boots fine. I still see the same errors about lightdm, but the pi now reboots in ~40sec.
I'm not going to mark this as solved, because buying a new sd card and rpi is not really solving the problem, but in the process of debugging I found out my sd card and eventually my pi were shot, so I got the easy way out.
Thanks all for the help.
