Funny I tried that storybook window at first too and I poo-pooed it because it has that ledge, but coloring it to the same color as the wall, it doesn't stand out as much. I just tried the storybook and the India one and those two are my favorite now, over the Uni windows. I used the wall with dado, chair rail, molding & baseboard and I like the way the gold trim lines up with the bottom of the India window (however this wall trim doesn't allow for your 2-step frieze Rox).
All 3 of these (uni, storybook & india) sit perfectly for table seating. I put the different colored floor tiles on the ground to show possible room sizes - four at 3-tiles wide and one at 4 tiles wide. (You could even use both - storybook on each end and the 3 india ones in the middle.)
Here's the storybook:
