I wonder if the system will let me boot into 'party mode' instead. That would be more fun than single user mode.

D and F also seem plausible. I'll have to try a few options and see which one works best.

Hmm, I'm not sure about A. Remounting the root filesystem read-only might not be enough to get the system running again.

E seems like a good choice too. Dropping to a root shell could give me more control to fix the problem.

I'm not sure about option E, but I think option C might also work to boot into single user mode.

I agree with you, Chana. Adding systemd.unit=single or init=/bin/bash should work.

B and C look like the right options to me. Booting into single user mode should help me troubleshoot the system issues.
