I think that's a good choice re 4A/B but row 10 on the way back is too close to the galley or my liking and there's an offset window.

I'd also choose the K side back so the sun isn't glaring in. Row 12 has a window blank and I've had row 11 before which is not too bad and also makes for a relative quick departure on landing. See post 402 for a picture
