The only part of mine that is out beyond the edge of the counter is the thickness of the door , about 1,1/2" . It swings all the way open, I have never noticed it being restricted in any way.

@Raimondi I understand this. I asked about the unfinished sides protruding.

Same as galanamedgalez8a. The cabinet enclosure covers the entire unfinished side. Only the doors stand proud of the cabinet. The doors open fully.

Here is what my side of the fridge looks like - it is Bosch 800 series counter depth. the doors open fully. I just realized now there is still a tiny sliver peeking out - i wonder if that can be pushed in farther? I don't really care though.

@RTHawk that looks great! I’d be happy with that install/operation combo. Thanks so much for posting a pic

These questions are answered in the drawings in the specifications sheet. Note that the opening is to be be 25" deep to appear as shown above.

As others have said, you follow the spec sheet. I believe the Bosch is one that has some different options depending on how far you want to be able to open the doors, etc. If your space is existing then you would temper your expectations with the limitations of the space. If you're designing new, then you'd decide what you want and what some of the other tradeoffs might be and size it accordingly.

Picture below from the manual linked by wdccruise. You definitely want to be able to open the doors fully so you can remove drawers for cleaning.
