Afghan x Skunk is a start, since you might keep plants small under leds, I've heard that one single cola might be beneficial when growing under leds, but that might depend on the technique. Basically you should look what kind of plants you would prefer personally, narrowing the input on strains possible.

I personally would look for nice small stock types, mostly IBLs. Maybe NL, Bubblegum - and some africans - but that is my personal weakness.

Then you should really grow out a bunch of them and look what plants perform best. Then you can select the best ones for further narrowing your aim - type of high, smell, pest resistance ...
Cross them, grow the offspring and select further (using the appropriate breeding techniques), keep a documentation, take keepers and evaluate your results, discard the unwanted ones.

Just a short skratch, otherwise you'll only end up with seeds that just happened to be produced under leds, not with specimens particularly selected to perform best under given conditions.
