Is a 450VA UPS enough for a modem / router?

UPS batteries in most cases don't have many recharge cycles. What kills the batteries is age. Your situation in Florida is different and location specific. The requirements for power backup systems are much higher. In my location the UPS units have few short power disruption events per year.

The current Bluetti model equivalent to mine is selling for $146 which is about twice the price of UPS of a decent quality. It has a three year warranty and the battery is supposed to be good for 3,000 recharge cycles. Over a couple of battery replacement cycles the Bluetti will come close to the cost of a less expensive UPS plus batteries.

For some unknown reason I prefer French Schneider Electric before Chinese Bluetti.

Who knows. The point of my original response to his post was let the OP know there are other options besides traditional/standard UPSs.

The unit you have is more like a large power bank, not an typical UPS. I see it sold in Canada as well, listed in "Camping and Outdoor" category, currently on sale for USD192 equivalent (USD276 regular), but comes with 2-year warranty. The advertised charge cycles are 2500+, but to 80%. This is common for lithium batteries. Perhaps similar to yours 600W/268Wh current model:

BLUETTI EB3A Portable Power Station | 600W 268Wh

BLUETTI EB3A Canada, 40 minutes to reach 80% charged! Just a ultra-portable power station that crazy campers will love.

This type of device is indeed more suitable for your specific needs in Florida. You may have more use of high recharge cycles and faster recharge times. For the rest of us in areas with less power interruptions - 100 charges and acid battery is okay. I also never had an emergency generator in any of my homes. You enjoy 20C now though, I "enjoy" -3C with -17C on the forecast. No place is perfect.

Just had my 950VA UPS alert me last night with the solid tone and green / red flashing LED that it's battery was dead, or soon to be, or other related issue. So today I ordered a new one delivery from store that's a 450VA. I'm pretty sure this will be plenty to back up the modem / router. The Printer and scanner aren't on battery, they are on surge only.

Just note that APC is good about supporting their older devices with Battery Replacements - I have an older Back-UPS NS1080, and the new OEM battery was pretty reasonable - $78USD with a pre-paid return label for e-Waste...

I agree...

The big battery banks are good for a purpose, but they are not really an IT oriented UPS...

Most UPS have some sort of SW that will indicate state of the mains power, and there, on the client devices, can trigger actions - e.g. a clean power off perhaps...

Going back to my APC Back-UPS NS1080 - modem and discrete router providing WiFi on a dedicated AP - During a "planned outage" over 18 hours, was able to keep up network for about 8 hours, when the WAN side failed because battery-backup on the carrier side for our local network loop...

Local side was good - but there, was pretty surgical about what would stay "up", what would do a clean poweroff (the NAS), and letting downstream gear go offline (soft or hard)...

WiFi was important - so that phones/laptops had access... to that end, I had WiFi on the phones after the 4G carrier cells went off-line due to running out of battery...

One of the few times I can compliment my cable provider - they kept service up the whole time - so as long as the modem had power...

Most UPS have some sort of SW

Yes, APC PowerChute for example:
