Dedicated AC line - Contractor wants to use BX instead of romex

I’m having a dedicated in wall AC cable run, about 40-50 ft. I was planning on using VH audio cryo’d 10-2 Romex but the contractor wants to use BX since it’s an urban area and more impervious to mice, etc.

Any thoughts on this?

Also I was planning on wiring the end of the run with an 20 Amp IEC connector so I could plug it directly into my Niagara 7000. I don’t know if they will wire it this way but I thought I could always do that myself later.

Ask him how much extra to run your 10/2 in FMC (flexible conduit).

If you're in a converted industrial building or similar it might be code. It might also be the contractor has run into that problem in your area. If possible it would make no difference if your special wire was run in flexible  conduit if the contractor agrees.

I live in one of those God forsaken red states and we're up to the most recent NEC.

Only commercial construction and over populated densely packed & infested cities require conduit.
Not in my red state. I was required to run through conduit in one of those areas populated by cows more than people. Single story ranch. You need to quit generalizing. If you are a licensed electrician you should know there are codes where conduit is required for certain applications.
