Yeah I would love to find a list of 3e FR modules from Dungeon. After a lot of though I have settled on starting Raider's of Galath's Roost from Dungeon #87. That being said, I think there is way more quality printed adventures for 3e FR than there was for 2e, despite 2e having had so many more FR products. Under Illefarn (1e but still), Halls of Eveningstar and Doom of Daggerdale are all that really come to mind.
Only thing missing from your printed adventures is the Cormyr trilogy (Tearing of the weave etc) and the Mysteries of the Moonsea book which is entirely a book full of adventures (though they are not fully fleshed out).
I did not know about the LGR and XGR adventures. Interesting, I wonder how easily they can be plucked and used.
There are also mini adventures disperesed throughout the FRCS, Silver Marches, Unapproachable East, Shining South and so forth.
After a lot of consideration I have decided I am going to start them with Raiders of Galath's Roost from Dungeon #87 (Skip Williams), then figure out how to teleport them to the Yuriwood area for Twilight Tomb. Raiders starts off with some heavy Faerun flavor but in a slightly more grounded way (dalelands stuff, Zhentarim, drow raiders, worshippers of Bane), while Twilight Tomb is also very flavorful for the setting but in a much more out there way. After that they should be around level 4 or 5 and I can head them towards Sons of Gruumsh or the various Mysteries of the Moonsea stuff. If it survives beyond that then Pool of Radiance, Into the Dragons Lair (assuming I can make these last two work with the timeline), trips to Undermountain, City of the Spider Queen etc are all fair game, not to mention all of the stuff that I could adapt.
I will also disperse Ravenloft, Spelljamming and Planescape throughout if the campaign gets to mid levels and feels healthy enough to keep going. I could also have a separate group doing Night Below if I can figure out a good conversion.
