I would have preferred that they took the Cute Cuddly Alien Space Nazi story even further.

Later in this post you say a homecoming arc would have taken time away from the founding of the Federation arcs. A three episode homecoming arc would have taken up the same amount of time as "Stormfront I&II" and "Home," and given season 3 closure (as opposed to what we got in the 43-minute episode "Home").
Seems to me an expansive Trek Nazi story would have been a bigger waste of time because it had
nothing to do with anything (and as you yourself have noted, doesn't even wrap up the TCW by telling us who FG is).
Well, in my homecoming arc we're not just talking about parties and crew members visiting family.
1. The homeworld of the aliens Archer stranded would stop in to demand that he be extradited for trial for piracy and murder (because without their warp core the crew couldn't escape pirates and some were killed).
2. Hoshi suffers from post-traumatic stress and it's possible she might not be returning to service.
3. The Lyssarian protocol prohibits the use of their larvae to create clones. They find out about Sim and are particularly outraged that he was created for body parts and actually murdered to save a human.
4. In the "Home" episode, there was no mention of the people of North Star or the crew's descendants from E2 (They're not even my kids and I want to know their fate).

Maybe we would have gotten some of that, if the show had been on a few more seasons. I don't begrudge the show for not doing it.
Neither do I.
I think they covered enough ground in Home and moved on to finish the series.
Right. The only ground I recall being covered in "Home" was Archer's actions in the episode in "Impulse" and his guilt over the things he did in the Expanse (which was Sham-Wowed away with a little sex at high altitude

).
And since it wasn't his fault the Vulcans on the ship were allergic to Trellium, the coverage of that ground was lame. There were plenty of witnesses (including T'Pol, who suffered the effects after brief exposure) yet no one but Archer was brought in to be debriefed, in answer to Soval's accusations, nothing.
Oh, and the xenophobia that emerged on Earth was handled with a bar fight.
Some of your suggestions I would be happy not to see as they are a litle too "fannish." I don't really understand the need to have every little thing resolved, and frankly there were too many things left unresolved in the Xindi arc.
Every little thing?

Season 3 was 24 episodes. I suggested followup on FOUR of them.
I am glad they just moved on and got to the Founding of the Federation..
I didn't know that invasion of the United States in WWII by the Nazis had anything to do with the founding of the Federation.
I wish we could have found out things about Future Guy, and all that, but then we wouldn't have gotten the Vulcan Arc, the Augment Arc, the Babel arc or any of those other great stories because some Trip obsessed fan wanted to get another story about Sim or Lorien.
Sim's dead. The story would have been about PHLOX.
The "Damage" followup would have been about ARCHER.
The Hoshi story would have been about HOSHI.
And the "E2" followup would have been about the DESCENDANTS of the entire crew.
Nice chatting with you.
