If there was a power outage it may not turn on (usually it starts up again).
Or if it was remotely shutdown.
If there's a power failure and it doesn't come back up when the power comes back on then it's not likely it's going to work right until you have a close look at it. There's probably corruption to the file system that needs to be repaired or you might need to reinstall, hopefully from a back-up.
As far as shutting down goes, well... Don't do that! Not unless you really know you don't want it on until you have not so remote access to it.
I suppose if you had two with some sort of relay hats, you could use the relays to trigger a restart from the opposite Pi.
Here's the thing about WOL. It's "Wake On LAN." It doesn't work well or at all over WAN. Most if not all routers block it, so you need a machine that is local to the one you want to wake to send the WOL signal. There's a web interface for the Pi written to to exactly this (although it runs on any web server).
