Sinister Secret of Saltmarsh - never played it.
Dwellers of the Forbidden City - Not really; though enclosed, the locations are pretty open to visit in whatever order you please, IIRC.
Speaker in Dreams - at first I thought "no", but I seem to recall it has a pretty sharp timeline; depending on definition, it's more of a "chronological dungeon."
Freeport trilogy - like Speaker in Dreams, more of a "Chronological Dungeon" than a dungeon in the traditional sense.
Steading of the Hill Giant Chief - though there are many ways to approach it, it's usually approached and handled in the manner of a "Dungeon" - plus, there's a good old-fashioned "dungeon" in it!
Slavepits of the Undercity - Typical Dungeon.
The Standing Stones - never played it.
Beyond the Crystal Cave - typical Dungeon, IIRC.
Isle of Dread - no; totally freeform in encounter matrix, and plenty of opportunity to move from one encounter to another. There are some small Dungeons within it, but the overall module is pretty freeform in encounters.
Dungeonland - Though it's a demiplane, it's still too open-ended for me to call it a Dungeon.
Queen of the Demonweb Pits - classic Dungeon. navigate the web, if you fall off the path you're probably dead!

Side Question:
I'm curious why you asked if it could be written in a single sentence in this case?
