"Trim" to me includes simple profiles for joining the boxes and making transitions to the walls or the next box. Anything beyond the basic boxes is what I consider to be trim.
Thanks,

Don't think I mis-understood you at all. I simply think you're not fully onboard the Euro train. There are NO PROFILES for joining boxes, simple or otherwise. The carcasses get screwed together and they're done. The face / plane of the door or drawer front(s) simple continue in one plane - that's the transition. when you get to a corner or a end wall you use a profile filler (to match your door and continue the plane) that is scribed to the wall just like you would a framed stile.
So, "trim" for you will be a profile filler and toekick that usually clips onto leveling legs - though practically no one installing euro will call that stuff "trim" Tom's two pics show how ends are handled by 99% of Euro cabinet makers.
here's one we did a few years back with , smoked glass uppers 3/4" end panels on the left with profiled fillers on the right scribed approx 1" wide. Notice the wine cooler doors are flush / in plane with the cabinet door fronts. pretty much the same as Tom's except it's lacquer and glass instead of veneer.
2nd pic is an inside corner treatment.
