CP1500AVRLCD3-R is a current model.

CyberPower CP1500AVRLCD3 Intelligent LCD UPS System, 1500VA/900W, 12 Outlets, 2 USB Ports, AVR, Mini Tower, Black https://a.co/d/cRKM77a

Amazon sells it for $190 new. At most it's 2 years old as it was released in 2022.

That's probably a reseller account.

They downplay deals so they can dissuade people from buying stuff they're trying to flip.

I would love to see the Li-On battery technology 'trickle down' faster to the consumer market. I've been experimenting with using a USB power bank and a USB 3.1 PD development board to power my various DC networking components.
The elimination of DC -> inverter -> AC -> router power brick -> rectifier -> DC has looses at each step.

Which one of these for a synology NAS?
This would depend on the nas model and your goal. If all one wanted was to make sure nas gracefully shuts down then you could go with a smaller size. If more run time is needed then bigger is better.

So which one to get to use with ubiquiti networking equipment?
GX model sold out.
Is simulated sine wave output good enough in these models?
What about transfer time from ac to battery power?

Not recommended to connect to a sump pump, since they will exceed the 900W power rating.

Would either of the two simulated sine wave models (1500VA) be ok to run a regular sized refrigerator for a little while? Or does it HAVE to be pure sine wave for that.

I have a 1500VA and it would not run my fridge when I lost power

If you're looking for straight DC UPS for small devices, that's a thing that's existed for a while: https://a.co/d/6H1XFD5 I have one of these that's 4 years old, still kicking, and another that's 2 yo running the stuff that can take PoE.

Refrigs generally draw way too much power (300-600W) to be run on this type of UPS. Even something like the CP1500PFCLCD rated for 1000w probably will not be able to kick it on imo and even if it did, it would not stay on for long before the battery was drained.

These types of UPS are made for electronics generally. That said, when using on electronics I still would only use the pure sine wave models.

My personal opinion is APC makes better UPS. The internal gut of my cyber power ups is cheaply made.

Quote from Tsumi :
A couple of power stations by Ecoflow and others are purported to have very low switchover times when used as UPS. If it's just powering low power DC hardware, just get a bluetooth-enabled unit, set the battery max level to about 85%, and reduce the AC charge rate to just slightly higher than the power consumption of your hardware to get maximum life out of the battery.
fans on EcoFlow might kick in even when not charging / discharging, which can be quite annoying
