Most of the "McMansion" photos I've seen criticized on architecture blogs are either middle-class houses from areas where basements are uncommon or cherry-picked examples of unusually bad design (many of which are actually custom builds!).

I think there's an issue with this premise. McMansions are not 'mansions' and the criticism stems from that fact. They are too small for the architectural features they try to cram into their facades (balustrades, numerous columns, far too many windows of awkward sizes). Also because they are small, they try to maximize the use of space leading to the exterior looking very weird due to overlapping roofs so individual rooms can be as large and tall as possible.
It strikes me as, conceptually, a distinct contrast to an 'average' Victorian home floor plan (which is probably the other closest thing to 'mansion' that an average person might think of living in), where even a very large home is going to have pretty tight and efficient layouts meant to maximize collective practical use of the space (especially with a large family or guests), rather than just giving a ton of square footage to each individual inhabitant.
Hmmm, actually it’s usually the case they have too few windows because windows (carpentry to house them and the actual window) is far more expensive than just having a wall.
But you’re right, they’ll often have a window that is incoherent with the rest of the house and/or in a weird spot when viewing the home from outside.
If it's got a 2000 sq ft footprint, with one story above ground and one below, that fits your description, but I don't think most McMansions tend to be one story—if they're 4000 sq ft, I would guess that many are likely to have about a 2-3000 sq foot footprint, with part or all of it having a second story (actually, rarely all, because a full-height foyer is a fairly common feature, from what I've seen).
I obviously can't comment on what you've seen derided as "McMansions", but I've seen a bunch of the stuff on McMansion Hell specifically (the blog the author of TFA maintains), and in general I wouldn't say they fit what you describe. Or, at least, some of them may not have a much larger livable square footage than a rural/suburban middle-class house, but they certainly cost appreciably more, because that middle-class house is built in a more or less standard manner, and the McMansion has a three-stall garage, four separate sets of pillared porches on the front, and three bay windows (in three completely different styles).
Go here: https://www.wausauhomes.com/search?& and play around, you don't really start seeing things I'd definitely call "McMansion" until you're in the 4+ bedroom category, and many of the 3+ are quite nice looking.
(I personally get much more annoyed by "attached/built in garage" because I know what that can do to the mechanical envelope of a house.)
