Seem to recall 7K is blocked out on the MEX route in at least one direction (maybe both) so 7J/K would be out. 7A/B would be an alternative but you do have the toilet immediately behind you and that puts some people off. I've not flown 7A on 787-9 that I can recall but have had 3K on the 787-8 a couple of times (the toilet is on the J/K side on the -8). I was initially concerned about it, but wasn't an issue for me in the end, wasn't disturbed at all. Your mileage may vary of course.
You could take 2 of the middle 3 (7E also has direct access) but of course no window and you may have another passenger in the remaining seat, so no obvious advantage to that.
Seems little point in going into the bigger cabin, and of course if you take 13A/B or 13J/K to get direct aisle access you are at some risk of noise from the bassinet seats immediately behind in WTP, if they are in use by an infant.
By the criteria you've laid out (not being stepped over), I think you've probably got the best options.
I always choose 7A when flying alone and 7A/B when with my wife. Foot traffic is pretty light and honestly once you have your TV on or are asleep you wouldn't even notice the cabin crew brushing past now and again. As for the 7K, yes, it will be blocked off as a crew rest seat for the LHR-MEX BA243 flights. It may become available closer to the time. It is not blocked for the other direction as the flight time is short enough with the atlantic tail winds to avoid the need for the crew rest. 13AB are ok, but as mentioned above you risk a baby in the front of WTP. Thus, my believe would be any of the AB or JK pairs in rows 6 and 7. Be aware numbers are fairly well down on the route right now, so I don't imagine you'll be bothered much either way.
