I work at an electrical supply store and if you want some good, quality lighting go with the cut in wafer lights. NDR is a reputable brand and the Razor series of wafer lights are absolutely top notch. You go ahead and get the electrical for the lighting ran as you normally would and then you cut a hole, with I think a 6 3/8 hole saw, wire the included junction box for the LED driver, connect it to your wafer light and then pop it in the drywall. They’re also color selectable so you can do soft white, cool white, etc.
No actual mounting junction box is needed as they have spring clips that hold the wafer lights themselves up to the drywall ceiling, and they include the LED Driver/junction box that will then screw to a joist or support beam.
Just thought I’d toss in my 2 cents
