If you check my comment, I will show you my current Dying condition that I have been able to test on the field.
It's 80 % the one from XP to level 3, with a few things changed and actually used in a DND game :)

This is a really overview.
I play a lot of WFRP. The fate point system is similar to option 1 and the critical system is effectively option 3.
And as a GM I’ll never get in the way of option 2!
