Based on some 50 F flights on CX 777.
My preference is 2A>2K>2D>>1A>>>>1K>1D.

I need to sleep and am easily disturb by noise even with earplugs. Twice, I had a group chatting behind in front of 1A which is the natural place to hold a conversation. Typically chat between some ID staff travelling in F and some of the crew. I had to get up after being woken up and tell them kindly to make less noise.
I find 2D excellent as I don't see what is the attraction of a window.
I will not fly F if the only seats I can secure are 1D or 1K because of continuous nois issues with galley.
Everyone is different, so that's just my personal comment.
