I’ve been using an APC battery backup for many years but am now expanding my setup. I am getting a Mac Studio and two Studio Displays and am connecting two 4Bay OWC Thunderbay enclosures with four 6TB drives in each. I will also have a few NVME’s downstream. I live in an area that gets frequent outages and very frequent “blips” that don’t cause an outage but do cause my UPS to sound off. Does anyone have a recommendation?

A lot of spikes and brown-outs with some total black-outs and switching to generator for a day.
Mines a server mount: Sonnet xMac server with a 2018 Mac Mini, 4Bay OWC Flex 1U4 Thunderbolt enclosure with four 16TB drives inside + New M2 Mac Mini Pro on top. Two 4K monitors, HP Plotter, HP Laser Printer, + my home office wired network. As you can see its only drawing 23%. I've had it for a year. Commercial grade. Say away from consumer types. No complaints. Does the job. Money well spent!

I just started using a Goal Zero Yeti as a UPS. I don't think you can use the tax credit for a UPS, but you can for a solar "generator". Costco has a 1000X with a 100W solar panel for $1400, so it ends up being just under $1000 after the credit. And you can add additional batteries that also get the credit.

I use a cyberpower pure sine wave UPS with my mac equipment which all have active PFC power supplies which don't tolerate cheap modified sine wave UPS as well. They run from $150 BF sales to around $200 non sale prices
I use this one for my imac

I am sorry but those are not pure sinewave UPS'. They could not handle a '09 Mac Pro tower where my APC SUA1500 could. Now, newer computers like a mac mini are fine but they apparently don't require pure sine wave power. That Cyberpower line is just mediocre consumer grade product. Besides would you trust a company that touts pure sine wave when it is not?
