According to the inspector, I need GFI protection for a hard-wired dishwasher and a garbage disposal. I see in 210.8 (D) that GFI protection is required for an outlet serving a dishwasher. Would a hard-wired unit constitute an "outlet" as well? Also, I don't see anything in the section about disposals requiring GFI protection.
 
Yes it is an "outlet." Take a look at the article 100 definition of that term. Sorry.

Yes, you need GFCI protection for the dishwasher. Your outlet is the connection box on the unit.

Outlet. A point on the wiring system at which current is taken to supply utilization equipment.

For disposal ,I would say no but 210.8(A)(7) can get interpreted in many ways in determining how to measure.

I agree, no GFI for the disposal per the 2017 code.
"For the purposes of this section, when determining distance from receptacles the distance shall be measured as the shortest path the cord of an appliance connected to the receptacle would follow without piercing a floor, wall, ceiling or fixed barrier, or passing through a door, doorway or window"
IMO the disposal is through a cabinet door & no GFI required.

If it's under the sink with a cabinet door in front of it then no. If no door then you need to measure the 6' to the sink to make the determination.

I agree with the DW needing GFCI but disagree with your statement on where the outlet is. The connection box is part of the utilization equipment and goes against the very definition of "outlet" that you posted. Specifically "a point on the wiring system", since the box on the equipment is not part of the "wiring system".

Now having said that, if the DW is hardwired, and no junction box (mounted on the structure) is used, then I can't say where the "outlet" is.

Well, you have to have point on the system where it occurs.

How about we say it’s inside the wire nuts that are located inside the connection box on the unit?:D

if you are hardwiring it then it is using the same type of outlet that a pendant light or any other mounted light is using... it still requires an outlet box. Here in UK we actually have some very nice such boxes that include a fuse spot and a switch, but never saw such in the USA.
That said, what with the call for just about everything to be afci and gfci protected in a kitchen, I would probably use one of those gfci no outlet switches above the counter with the dishwasher wired to the load side of it. Not sure if the inspectors would allow a single gfci outlet to do same thing as have not read the code in depth enough to see if the dishwasher circuit in the USA is required to only serve the dishwasher or may serve an outlet as well... in Jamaica the inspector has decided that it may only serve the dishwasher but is considering my position on the gfci outlet allowing one to disconnect above the counter... He expects to have my answer on that when I am next in the island...lol.
