I would stay in 1AC. A has a slight disadvantage, as the screen is a bit offset due to the curvature of the plane.

There is not no storage. There is a shelf under the screen, you can have a carry on under the ottoman (which is where I keep what I need but don't use)

Apart from that, the window seats have a shelf where you enter the seat, a magazine storage next to the screen, there is a storage area above and behind the seats. The window side aisle seat has a cubby where you can put things. But the center seats don't really have anything but the under screen and ottoman options.
