2 stage vs 1 stage furnace

I am looking at Lennox ML180EK 66,000 BTU and EL280EK 88,000 BTU models.

Is there any reason someone would take a 1 stage model over a 2 stage?

The way I understand it, the Elite would operate at 66,000 in Stage 1 unless it needed more power and only then would kick into stage 2.

I have a basic Google Nest, do I need anything different if I get the 2 stage?

For context, my current furnace is 88,000 but short cycles due to being oversized. I’m looking to downgrade in terms of power, but think it could be worth it to keep extra kick for the really cold days.
