I shredded a few carbon resistors and noticed that many have the
carbon layer laid out in a spiral pattern around the cylindrical core,
up to several turns.

I also shredded a few metal-film ones, but could not figure is the
metal was on a single layer or not, and how it was connected to the
leads.


I wonder which best approximates a non-inductive resistance.

I am no expert on this, but what you describe as carbon is perhaps carbon
film
Your best bet for low inductance would probably be the carbon composition
type. These are found in radios from the 60's-80's- Mouser is still carrying
these.
In appearance they look like a perfect cylinder- no bumps on the ends.
