One practical thing is to treat the ONT, router, and any switch you actually
need as one small critical load and measure that load before buying the UPS. A
lot of the little network boxes draw less than their wall warts imply, so a
modest UPS can run them longer than expected if it is not also carrying a PC,
monitor, printer, etc.

I would also do a planned pull-the-plug test while nothing important depends on
it.  If the ONT and router stay up but the provider's upstream plant drops, then
more battery on the customer side will not buy much.  If it stays online, then
the UPS runtime number is actually worth optimizing.
