I think the "obvious" would be more friction, not less.
I guess what's obvious to me isn't necessarily correct. ;)
To me more material would seem obvious to cause more friction, but apparently not.
I did use a very thin cord for an auto block once, and it didn't work super well. It took too many wraps and didn't hold its shape as well as other options.
It depends on the rope and prusik diameter combination along with what prusik wrap you use as to what the effectiveness of the hold you achieve is. Along with other variables, such as, the types of materials (sling with rope compared to rope with cord) used.
I would try out different combinations on the ropes you will use before you trust your life on it while 100' off the ground. Better to know how the gear you use will react when called on.
A greater difference in diameter usually locks better. So 5mm cord on a 10mm rope should work better than 8mm cord on a 9mm rope. At least that has always been my experience. 5kn should be plenty, the loads should be static.

I agree. Considering extremes, 1mm cord would grab extremely well as a prusik, whereas 13mm wouldent probably grab at all, tat is unless you are using it on a 2" mooring line.
