The Corn is a great asset to have. Settling in the original spot would have been a solid choice, if it had been done one turn ago.
For this turn, however, it's a choice between the Corn and the Stone. Comparing only the original location with this turn's location of the Settler,
I would still go with the original location of the Settler, since there are no flood plains nearby, and having only one Food resource with no flood plains would not lead to a great capital. But the Stone would still be accessible as a resource, even though it would not be in the BFC, if you chose to settle in the original location.
Now, if you consider the tile 1N of this turns's location of the Settler, it's a choice between gaining the hammer output of the Stone and losing a turn (because out of the two other choices, the Corn is the better choice). In this case, you're gaining the Stone purely for its hammer output, not its resource benefits.
It seems you could make up for the weaker hammer output for not having the Stone in the BFC, if you decided to forget about building Stonehenge. That way, you could save your hammers on more important things like...the Pyramids. Remember that working the Stone tile means only 1 Food for that tile...with so many forested plains in the BFC, I don't see that as a huge gain.
So, I'd say move to the original spot, with the intent of skipping an early wonder and focusing on building the Pyramids.
P.S. Also remember that moving to the original spot gives you access to some hills to the east, which can help towards construction of the Pyramids.
