Wall cabinets in my standee

Hey gang, looking for some opinions on how to design the finished look for my side wall cabinets in my trailer. The roof drops about 4” front to back, so the ceiling is not parallel to the floor. One cabinet will only be 18” wide and will be vertical floor to ceiling shelving, so the uneven top won’t be noticed. On the opposite wall though, will be a sink base with cabinets above, about 50” wide, X 12” high. This one will be very noticeable. Plus, it’s directly line of sight from the door. Kinda the first thing you’ll see. Curious as to opinions on just running the face of the cabinet all the way to the ceiling, and have a tapered cabinet? Hang a true square cabinet and have tapered open space above (this space could only be an inch or two, not enough for storage)? Or, square cabinet with a filler strip, offset either front or back a couple inches, leaving a cornice, or a small cavity?
The open space option would mask any waviness in the ceiling
Thanks!
