Despite some of the comments here, I suggest that you don’t overthink it; just buy an APC Back-UPS 600VA and be done with it. You have relatively low power requirements. The UPS will provide some surge protection (490J), several minutes of uptime, and a USB connection for automated shutdown.
The 600VA unit is less than $100 USD and replacement batteries are about half that. I’ve been using several of this same model for years without issue and we have many brown/blackouts being in a rural BC community. The batteries have lasted me 4-5 years.
You can always plan for something more significant down the road, if your hardware or needs change, but this should do fine in the interim.
Lots of great responses here already. In terms of simplicity and ease of maintenance, Hugo is going to be the best solution with its single binary, built-in features, and ease of setup/use.
