What you propose is fine. It's covered under the tap rule. DO NOT run romex straight to the unit. Romex is only rated for 90C and the unit needs 105C wire (as it came from the factory). Use the j-box and the pigtail, as you said.
Now that's what I call a firewire!
Not service entrance, drops a.k.a. pendants. See NEC article 400.7(A) for a number of examples where flexible cords and cables including Sxxx are permitted in permanent installations.

$30 worth of wire? How much did the house cost?
Appliance protects itself. The fuse/circuit breaker is there to protect the wiring only. And in fact the wiring of the house. If its hard-wired, then it becomes part of the wiring of the house. Either way, the CB is for the house wiring. The grill can piggy-back on this protection if it sizes its wiring to match.
Among other NEC permitted uses for flexible cords is "appliances where the fastening means and mechanical connections are specifically designed to permit ready removal for maintenance and repair..."
I think the best answer, if the device is listed, is by Calvin Henry-Cotnam that the cord is part of a factory assembly.
