Yes, that's correct about switching the neutral conductor.

Let's see if we can help you with your understanding of a SDS
The reason I posted this is from experience, a very respected local electric company ran EMT into the top of a transfer switch, nothing wrong with the conduit I could see, but years later the painters came and pressure washed the building before painting, a month after that I was out there picking washed down old lube particles out of the switch mechanism. They could have just as easily LB'ed into the side/bottom as landed straight in the top, the water intrusion did not come from the hub or anything nearby, it came from further up the conduit.
I agree it is generally best practice to avoid top entries into something that has lots of "stuff" in it like an ATS. EMT compression fittings often leak no matter how careful one is. That said, personally, i am confident I could do the install the OP has without issue due to the short length and by choosing the proper fittings and materials.
Why don't you focus on actually answering the OP's question rather than blabbering on about a bunch of irrelevant stuff and getting a bunch of that stuff wrong?
Correct, I am not and never thought about coming through the top of the ATS. A neighbor of mine had a supposedly reputable generator company (also who installed my parents but not near as bad) install theirs last year and they came through the top of the ATS. I'll post a picture but it's an all around awful install.

I don't see an issue with the reducing washers. The general rule is that conduit entries do not need to be watertight if they are below the level of uninsulated live parts (technically that is in article 312 and not everything is an article 312 enclosure). I use RW's all the time. Where things have concentric or eccentric knockouts, I usually rip them all out and use reducing washers cuz I hate ringed KO's
Austin, Huffman, Hammond Manufacturing, all make a lot of various electrical enclosures.
Yeah I found some hoffman oversized covers. But am going a different route.
They require the center of the meter at 6ft. Yeah, one they disconnect the service they require an inspection and the inspector has to send them the okay to reconnect.
No, but it is a violation to do so without securing cables either to the enclosure or to the end of the sleeve (maybe that would be easier to do with a box at the end of the conduit, so it's no longer a sleeve).
I don't really have the room for a box. I had to throw a 45 on the sleeve. I'm not really fond of how close it is to the roof decking though.
What about meter centers at multiple occupancies? Pedestal type equipment with single meters are never that tall either.
I would be surprised if they required single meters to be 6 ft, that seems quite high to me. Usually I see 5 ft plus or minus as a spec I'd be real surprised if they didn't provide a range.
