I'll add a #protip about UPS. Instead of getting Cyberpower or APC, I recently picked up a EcoFlow River 2 Pro[1] (portable power station). It has 768Wh capacity and 800W output and pass through charging. Crucially, it switches fast enough to not cause any outage to any of my gear (Ubiquiti, HP Proliant, Raspberry Pi, Synology). As a bonus, you also get the ability to do solar charging and USB power outlets.
