Nice setup, but we can all pretty much agree it's overkill for most. My ISP is fairly reliable and outside of infant death, most network elements have a pretty long MTBF. I run a similar set of WiFi gear. I've a couple PoE powered Unifi UAP-AC-Pro spread around the house, all connected to an 8-port Unifi PoE GigE switch. Routing is done with an EdgeRouter lite, which as it turns out is capable of line rate GigE. I have a low power industrial computer with 4 cores and 8GB memory that runs various services mostly via docker or vagrant. It consumes about 12w. It's all powered by a 750VA APC SmartUPS. I get almost an hour of runtime on the internal batteries. I may add some external batteries at some point, but most power outages in my area don't last longer than 20-30 minutes.

Power outages are fairly common in my locale so that's what I've primarily optimized for. Cable modem + WiFi hub on one UPS, desktop on another. Desktop stays on through short (<15 minutes) outages, wifi+internet for 3-4 hours. Power is still my primary point of failure, with probably 1-2 days of outages longer than 3 hrs per year, although in many of those cases the cable will also go out.

  > 1-2 days of outages longer than 3 hrs per year Not trying to be a dick, but does that count as "fairly common"?

    I think so.

    I mean, it's not common enough for me to spend the money on a backup generator, but it's common enough that you need to at least consider how long you can stay in a house without power, in what weather. Eg, my house will stay warm enough that I don't need to worry about me or the pipes freezing after 1-2 days without power in the winter [although it gets quite nippy after ~18 hours]; if the power is off for more than 3 days in the summer I need to do something or the chest freezer will defrost enough to spoil). Shorter power outages are more common; 10-ish power interruptions of less than ~2 hours per year. It's not like, developing or failing nation bad, but it's not great, especially when the problem is always "a tree limb fell on a wire".
