This would have to be a shielded cable, this would be a good starting point, go for Double Shielded Premium D-sub 25 Position DB25 Male/Female Cables - Fully Populated, Double Shielded
Your Torch Grounding and connection should be as per the PDF
I'm not saying anything. I just followed the Hypertherm recommendations in the document and a friend donated a very old "star" grounding point and set up my stepper motor cabling very carefully with noise in the back of my mind. Having 24 volt electronic controllers also helps as the higher voltage is less susceptible to noise.

Will a plasma cutter with pilot arc be a better choice regarding emi? .... a recent google search reveals that it reduces emi ...

Pilot arc may still have HF start. I think it may be a bit easier to shield than non-pilot arc, as the return path for the pilot arc is in the torch head.
What you want is blowback start, which I think is always pilot arc. Blowback doesn't use HF, so much easier to deal with as far as EMI goes.
What exactly is blowback and how does it work?
