Lights and seeds, Autoflowering

I'm going to shortly start my grow two plants max , found some nice seeds that are feminised so males wont be a problem. Ive sorted fertilizer, 99% sure im going to use soil.

Im not 100% sure what to do with my lights though. Ive got roughly 3ftX1.5ftX6ft. At the moment i'm looking at led grow light.

Which ones would you recommended ?

Seeds wise im looking at getting either feminised northern lights or a autoflower feminised pyramid galaxy ( its ahybrid of Afghani and Northern Lights) supposed to be very high yields.

Any opinions on seeds does it matter if they're expensive / recommended strains?

Any help is great

So many light choices. It can be daunting. What’s your price range?
Start with fems. Way more forgiving and user friendly as a 101. Where you sourcing seeds from?
