Power outages are frequent enough that I invested in a 100AH battery and inverter to keep things going - the local fiber loop remains online as the local POP has batteries so I only need to power the ONT.

My house is brick/mortar so I need 2 AP's to cover the entire house - the AP is one kids bedroom - she insisted a wired LAN connection for her PS5 (online gaming and ping/lag) so I needed to power both a small switch and the AP - got a 12V battery system for that.
