When Dad, an electrician, had to do it he pulled the wire through

requiring protection" or "protected by existing structure"

You are quite correct in that, but it's not a big deal to hang the
boxes and tie in inside them. Using THHN offers many advantages
over pulling NM through conduit, and makes the transition matter of
little real value.

Residential electriciand don't usually have rolls of individual wire
on the truck as (at least here in Ontario) it is VERY seldom used -
and was used even less back before Dad retired.

I'd be surprised if residential electricians did not have THHN on the truck.
There are times and places for it even in residential wiring. If they
don't - Home Depot is just down the road. I'll agree that it is not a
significant percentage of residential wiring, but it's not at all an
uncommon occurrance, either. No matter - for the job at hand, any
residential electrician would not find it unreasonable to use conduit and
THHN in a given application. I don't know when your dad retired, but I've
been wiring for over 25 years, and I'm way older than that implies, and I've
seen plenty of conduit with stranded wire that pre-dates my arrival on
earth.
