"Any help with a placement strategy would be appreciated"

I'll give it a shot.:jointsmile:

Since moving the plants it not an easy option, it would seem wise to build "flexibility" into the light placement.

Unless the following stab at advice actually has some merit.

Indica will generally be squatter and have broader leaves, (better at gathering light, but also obstructive.
It will also finish first, generally.
So, I'd put in on the outside just to make the scrog easier.

Aloha ya ol' cow poker.
