But with most people using CY cable right from motor to cabinet, should I be cutting shorter and using a longer run of CY - or does the closed loop negate the need for shielding?
I tend to cut the motor wires short and use shielded cable, but I have used them with the supplied cable and not had any problems. If it was me and you don't have any CY cable then I'd use it as is. You can always change it later if gives you trouble.
The encoder cable is usually shielded so it won't give you any trouble.

Cut these short as possible and use shielded cable.

Doesn't matter it's AC alternating current so it bounces both ways so no polarity.
