Here's the MSD of the Olympic class U.S.S. Nobel created by LCARS 24 and myself for inclusion in the next release of LCARS 24 for nitpicks and suggestions. The length is as extrapolated on Ex Astris Scientia. In original laying out the components, I envisioned the ship as being a multi-role medical transport workhorse, designed by the Federation to be equally well-suited for natural disaster relief and combat triage, as well as transport of precious medical cargoes and large numbers of passengers.
The number of windows on the model alone seems to indicate a lot of rooms, so it was my thought almost the entire ship could be used as one big medical ward, or for passengers. The large cargo decks along the upper secondary hull were also based on lack of windows in that area and the two large airlocks on either side, as well as adjacency to the obvious rear shuttlebay. I originally had the deuterium tankage in the 'hump' that the nacelle pylons came off of, but it was LCARS 24's suggestion that this should be another, larger shuttlebay to aid in disaster evacuations and so forth, which seems to match pretty well with the visual evidence - why else bother to have it be a separate hump?
A few relevant references. First, side view from the Star Trek Encyclopedia:
