Does the NEC require armored cable or conduit for a new thermostat run?
I have to go through a wall into the utility room and about 3 feet
horizontally to get to a box where the zone valve and thermostat wire meet.

Low voltage wire does not need protection inside a wall.

You can go look it up in the NEC. Or ask yourself if you've ever seen
a low voltage thermostat installed that used conduit or armored cable.
I've seen plenty, including new construction, never once a conduit or
armored cable. We don't even typically use that for 120/240V AC.

It is pretty common in commercial and they might require it in a
mobbed up union city like Chicago or New York for residential.
Chicago and New York traditionally required a metal wiring method for
all residential wiring but I hear they may have softened up a bit.
Chicago wanted EMT and New York leaned more towards AC cable.

On line voltage thermostats it's not uncommon - but you don't see it
on 24 volt stuff.

We ran cat 5 and coax in conduit in commercial.

I haven't seen wood in a commercial building in 40-50 years and it is
used in most new residential down here. The only wood in the houses
my wife built was in the load bearing walls of a 2 story and there
were not that many 2 stories.
In commercial the BICSI standard is 3/4 EMT for video, voice and data.
The fire code calls for a metal wiring method for fire alarm and
control wiring, typically MC cable.

The units that use switching motors might help noise issue with conduit. My
thermostat was radiating lots of noise. I cut down at source inside furnace
using filters, even on AC feed. I still have some noise.
