I’m planning on sticking one of these somewhere, possibly near the bottom of the seat. The single pack is currently sold out.

If you really want it and can wait, I would put it on. It will very likely delay you getting scheduled though. You can see my lack of success in my signature.
This is one of the biggest reasons I will be buying my first ever extended warranty through Flood Ford. All of these LEDs are supposed to last for a very long time but I've seen enough fail to know it's a bunch of BS.
Remove the tonneau from your build. That could serverly delay your order or prevent it from even getting scheduled. They are only doing something like 5% of orders with them. It is extremely easy to add afterwards.
My list:
Bakflip MX4 hard trifold tonneau
Tuxmat floor mats (far superior to the crap Ford ones with zero coverage under the gas pedal)
Spray in bed liner with Ford rubber bed mat on top
Lasfit LED bulbs for the reverse lights and 3rd brake/cargo light
Tailgate letters
Rokblokz mud flaps
