With a handleless door 19mm is just enough to open the doors, but not enough to take out the glass shelves. We mostly sell Siemens and Bosch (they're really twins), no problems with the veg/freezer boxes. Some of my customers are ok with the shelves staying in, but others add a filler of thicker panels on either side of the tall cabinets.
Because the thicker panels don't fit in the slim lined top and side panel of the cooking are, you could make the countertop 65cm deep, so it will stand out.
I'd also suggest removing the vertical 'handle strip' on the left of the oven. Hinges on the left side, it'll be fine. Also, pick a fridge cabinet without the little panel on top. There'll probably be a gap when opening the fridge door, but it'll look better on the outside. (Have a shelf on top of the fridge and you can store some large plates or oven tray there, just make sure there's enough ventilation for the fridge.)
Or.. Add another 'handle strip' on the right hand side of the fridge. And keep the strip left of the oven. Balance.
