I have no knowledge of a chemistry that allows sub-freezing operation. I'd double-check that -40F includes both charge and discharge.
I put a 20Ah LFP battery in the Prius 7 years ago and it has no BMS and no provision for dealing with sub-freezing conditions, and it's still working. That said, it doesn't usually get much colder than freezing, and freezing conditions don't usually last long. The stock battery bracket was capable of securing the smaller battery dimensions.
If you go with that expensive battery, I'd make sure the warranty terms are generous.
My solution would probably be a battery warmer that kicks on automatically when temps drop below freezing, and place the battery in an insulated box. I'd carry a cheap portable jump pack just in case an issue with the battery develops (I do that in all my vehicles anyhow).
This battery looks interesting to me;

I've started taking a practice quiz for getting a radio license. I might be able to pass the test without studying because my electronics experience helps with many of the questions, and I'm a very good multiple choice test taker.
