Few commercial EC will use #14 for anything other than perhaps control wires.But if no local rules or specs then go for it.

I remember way back, when I was a little helper, hearing the same thing, along with the 100'-max-between-pullpoints limit that also doesn't exist.

I love these old myths. It would really be interesting if we were able to find out how they started.
Alas, most origins are probably lost to history.

Don't leave out breakers panels near "water sources".
14gauge on commmercial for power supply is one of those things that is just never seen, but it's not because of a code restriction.
In alot of places, including the northeastern Ohio area that I'm in, residential projects don't have electrical prints. Residential project are inspected to code only.
Commercial projects are different in that they must have prints. Those prints must be approved by an architect or engineer (and the AHJ plan reviewer) and apparently they are taught not to include 14gauge conductors for power distribution.
Commercial (and industrial) projects have 2 minimum requirements enforced by the inspector, code and prints. We require to installation to follow everything on the prints. It doesn't matter if we think it's important. The architect or engineer stamped it. That's the way it has to be installed.

There was a thread a few months ago titled something like "old wives tales" discussing a lot of these myths. I'll see if I can find it.

Its sounds like a Division 16 requirement.
Typical are stranded only, 3/4 minimu size conduit, steel compression fittings, etc.
I use 14 for instrumentation and control power.

If you haven't heard a good rumor (or code myth)by 9am - START ONE
I hear they are going to require inspectors to take a class explaining the NEC and electrical theory before they are allowed to make any inspections. I also heard it is a 30 second class because they already know it all.
Rumor has it they are going to start training electricians next.
