I came to the same conclusion as Gator, that settling NW to get the FP-Wheat would give us a food rich but shield poor site. That doesn't mean that the northern side of the Wheat, if it is there, may not provide enough shields to suit our needs, but that would require at least 4 turns to get the settler there, too many for my taste.
Settling on the desert tile to the south provides enough food but may also be short of shields. The beauty of this site is that there are a number of grass and forest tiles which may yield BG's for us to use. From what I can see, it may also be shield poor but we have a better chance of gaining those shields. We also can cut the forests for a temporary increase in shields for a Granary or other build. An industrious worker requires 5-turns to chop for 10 shields.
Should we decide that south is our best bet, I would not waste a Scout move to the south. I would send the scout to the western mountain and then north to confirm the wheat. If the wheat is there and there are suitable shields available, the risk of pushing out a settler quickly may be justified. With citizens working unimproved tiles, depending on how we prioritize worker actions, that means 17 to 20 turns for Washington to reach size 3. That gives us time for either a warrior or a scout before the settler. I would prolly build a warrior for MP and security.
There are many worker turns needed to get this site up and running. If we push an early settler, we may want to pump an early worker or two from the second city.
There has been time enough for comment, imho.

Capt, if you have enough info to decide what to do, please proceed with the first 20 turns. If you would like more guidance/advise, please let us know and I'm sure we can easily create more spam.
The roster, then, is:
Capt Buttkick - UP
Nemesis - On Deck
Gator
Bluebox
Leif
Willow - Having a great vacation!
Good luck Capt.
