If you like the King Authur vibe, try Cormyr. Waterdeep is good if you want a more racially diverse setting, you want to include pirate adventures off the Sword Coast or if you want to dungeon delve (Ruins of Undermountain). There were so many really cool accessories for FR from 1st to 3rd edition out there that you can find all sorts of different region/city settings, from dark goth, frontier cities, jungles, and even asian (Kara-Tur). The city with the most source material is probably Waterdeep.
Here's a list of all the FR Region / City accessories:
Anauroch (desert), also has a 3.5 update.
Calimport,
Castles (Box Set),
Cities of Mystery,
City of Splendors (Waterdeep, many different edition versions of this too),
City of Waterdeep Trail Map
City System,
Cormanthyr Empire of Elvesm
Cormyr,
Cormyr the tearing of the weave,
Elves of Evermeet
Empires of the Sands,
Empires of the Shining Sea,
Moonsea,
Moonshea (Isles),
Netheril Empire of Magic,
Pirate s of the Fallen Stars,
Silverymoon Gem of the North,
Skullport (tie-in to undermountain and waterdeep),
The City of Ravens Bluff,
The Jungles of Chult,
The North,
The Savage Frontier,
Volo's Guide to (cityname here, lol),
Waterdeep and the North.
And that's just a partial list. Reading those will help you figure out what city you want to play in or make your own. I personally have just always loved Waterdeep because of the diversity of races, classes, etc. It's also has Skullport, the Ruins of Undermountain, and other kind of tie-ins too. The city is so big it has basically cities within cities (or wards). Each ward has a totally different feel to it. Anyway, hope this info helps.
