LEDs in New Construction - Class 2

New construction, planning on using some low-profile LED fixtures, rather than installing traditional cans. Something like this: https://images-na.ssl-images-amazon.com/images/I/611KrfPQaTL._SL1200_.jpg
(not necessarily that exact fixture, I just grabbed something of the sort for visual reference)

I believe that to install per code, these need:
NM cable @ 120V run to a Class 2 listed power supply. Power supply being an in-wall power supply unit, a surface-mounted unit, or one installed in an accessible box.
Class-2 In-Wall rated wire from power supply to fixture locations
Connections at fixture locations with WAGO connectors, inline splices, or some other permanent connection (no box)

Seems pretty straightforward, but I wanted to make sure I have it right before forging ahead.

Thanks
Dave

I'm curious as to your preference to use these vs traditional housing and LED trim.

All of them I've seen have a power supply that installs in the ceiling above the fixture, and have a short 6" or so lead to connect the LED.

The traditional housing route is a bit of silliness when you think about it.
Install an expensive housing that's designed around a 100 year old light bulb design (~$20 for a 4" airtight IC housing)
Buy expensive trim for the housing and an LED bulb designed to look like a 100 year old bulb, or buy a retrofit LED lens/housing (~$30)
In for $50 per fixture and there is a ton of unnecessary equipment above the ceiling that's not needed. Plus, they can't be installed directly in line with a truss or rafter.

Or use a purpose-made lamp where a single LED driver can run multiple lights. Picked up a 7-light kit, UL listed, IC rated, for $180. Half the price of the retrofit route, and I can hopefully get a tighter seal at the ceiling as well. Planning on running the romex to an outlet inside a kitchen cabinet. Surface-mount the sizable power supply, then run it's output back into the wall to the fixture locations.

Also picked up a 4-light set with a power supply that'll fit inside a 4" square box. Placing that inside the adjacent closet with a blank cover plate on it.

Also Known As "Disk Lights", surface mount to 4" light box, direct connect to 120v building wiring.

Man that's super high. I pay $7 for an IC housing and $14 for a Satco LED trim. Plus, the trims just look nicer than the disk light.
