From a practical point I'm confident that no Starfleet, Klingon or Romulan engineer would have constructed their ships the way they did, unless it was absolutely necessary for optimal FTL performance.
If there was an optimal shape or design for FTL performance we'd see all races use it. Instead we get the saucer Earth ships, the long-necked Klingons, the arrow-like Tholians, the spherical First Federation, etc.
Agreed, it may not be necessary for FTL performance but might be a proven reliable Federation design and eases the task of performing maintenance and repair for Starfleet engineers.
Someone like Scotty could fast and easily fix (or sabotage) the warp drive of the Enterprise
, the Reliant
or the Excelsior
but might find this more difficult and time-consuming with an alien design and/or one that has less than two warp nacelles.
