2nd floor fishing wire

I want to add some wall thermostats for baseboard heaters.
The existing source wire for the baseboards runs inside a type of quarter round. It's an L shape quarter piece of wood hollowed out with cable inside it like a raceway, but it didn'td seem to be up to code.
I could run the cable below the floors but I assume that means destroying the drywall on the floor below.
The wall is lathe and solid wood behind that so not sure if I could run nm in there as it wouldn't be protected well.
If I go with the floor option, does it involve cutting a small square every 24" (old joists) and then trying to fish through that or could I cut notches in the joists to make it easier. It's cross hostsj to make it harder!

Any other easier options?

How old is it? May have been OK in 1920.

What about going up to the attic, over, and back down?

Building is from 1900 but the wire is nm so must have been done later.
there is a 3rd floor above then attic so not easy for the 2nd floor.
I could fita 5" hole under each joist and then use a 6' flex drill bit or just a right angle drill?

Where is current t'stat? How often would you be changing it? A t'stat located on the baseboard heater makes the electrical connection easy. I am assuming the heater requires 240 vac and therefore the t'stat must be a 2 pole switch. An electrical cable for this type switch, mounted on a wall. down to the baseboard heater connection is stiff and difficult to work with in my opinion.

Existing tstat was on baseboard heater but these are not very accurate plus I want to upgrade the apartment.
