American 787-9 Business seat selection

I'm a solo traveler flying between DFW-BNE next month on an American B787-9. Currently no window seats available and the only choice is between the center seats 1H, 7D and 7H.

What would be your choice given the above if no window seats open between now and the departure date? I think I read somewhere that the row 1 seats have a slightly larger footwell (I'm 6'2).

Thanks!
