You will most likely be best off with the 7l on 5sa123. Make sure that you run a 5s2p setup, 2 packs of 5s in parallel, as the 7xl can draw some juice, and a single 5s pack will drop alot of voltae trying to keep up.
what does 3-5s mean? Is this the range you will be running, or you don't know yet?
The 6xl would run far too hot on anything, even the 7xl gets too hot... the 8 or 9xl would be perfect. IMO

So is it 3, 4, and 5s packs that you will have? Or you will be purchasing a 3, 4, or a 5s pack for this setup?
Sorry for not understanding...
