"crawling through Jeffries tubes will continue until morale improves" -A quote from an anonymous chief engineer of the ambassador class when welcoming the new enlisted.
Sure we chose the big hull, but we keep selecting speed options which cost volume and soon we'll end up with the thin hull's speed and volume, just at a greater cost.
The impulse engines are installed without much fanfare: the Type-5 in the aft saucer section is a process the drydock team can do by rote, but the Type-7 proves more of a challenge. The two thruster units that make up the engine are substantial things, each consisting of two fusion reactors and an acceleration chamber that can put out astronomical amounts of impulse power. They are also much more demanding in terms of precision, where even a micron misalignment could introduce turbulence into the entire assembly.
But with them finally installed you turn to the issue of weapon systems. While not strictly speaking a requirement, you have a firm obligation to provide a ship with nearly a thousand crew a solid defensive armament if nothing else. Here is where the earlier successes of the Type-9 come back to introduce complications: the design teams at Starfleet Tactical have already increased the number of emitters that can be daisy-chained together into a single weapon array. What is more impressive is they believe it can be integrated into a whole-saucer weapon, with a long strip covering what would take five separate arrays under your original plans. The resulting nadion streams would also be much more concentrated, increasing firepower.
The second consideration is the torpedo armament. The standard armament is two launchers forward and at least one aft, but here Tactical has another major proposal. They have pioneered a new rapid-fire torpedo launcher which can fire four photons out of a single tube in less than two seconds. That would more than double the forward payload that the Ambassador could unload in combat conditions. The same could be applied to an aft launcher for full coverage. It's an appealing option, but burst firepower isn't everything.
Project Ambassador must be capable of long-range exploration and independent scientific investigation. It must be able to provide diplomatic amenities and appropriate quarters for dignitaries. It will ideally be capable of engaging on equal terms the Klingon Vor'cha class.

We can get antimatter storage to make up for the increased ammo consumption.
With impulse engines now on the saucer and the neck (attached to the secondary hull) it should probably occur to someone to consider saucer separation. If not on this design, then shortly.

On the one hand, burst fire isn't necessarily what we want on a deep-space explorer - we don't want to encourage the ships to run out of photons. On the other hand, explorers in Star Trek are likely to run into the weirdest bullshit, and you never know when extra firepower might make the difference. On the gripping hand, I'm concerned that there's no drawback called out for either of these other than prototype status.
I think I'm going to go with normal photons just so we're not overloaded with prototypes on our vessel designed for long cruises outside of inhabited space. At some point that's got to bite us just for game balance.

I think it's time to slow down on the prototypes a little. We've already stuffed a lot on this ship, and we do want it to, you know, function. The basic Type-9 array is already extremely effective, and the worst case failure scenario of the strips is probably some kind of catastrophic cascade failure on the strips and potentially the power grid as a whole. But by contrast, the failure state of the new torpedo launchers is that we have an unimpressive torpedo armament, which isn't good and probably kills our chance of succeeding at our Tactical goal but isn't the end of the world either.
