Six year old thread, dudes. If this guy hasn't figured out what strain to use by now, chances are good he isn't going to!
To answer the question, in my opinion, for a new grower with limited vertical height, the best choice is either a pure indica plant, or a strong indica dominant hybrid.
This will be easiest to control height, and will finish fastest. Fast finish is extra good for a new grower, because it limits vertical height, limits the chances for problems to develop, and helps build experience quicker. Indicas are also usually easiest to manage from a training/pruning standpoint, and most of them will do well with minimal/negligible training.
Yes, its *possible* to grow hazes or other sativa dominant plants inside limited spaces, but that's probably the single most challenging type of indoor grow, and I'd reserve those for experienced growers, not for individuals just starting out, let alone starting out with an untested and short new setup.
In terms of specific strains, there are any number that could work. Personally I would NOT use an auto for this, because I think there are high quality regular/photoperiod plants that will work just as well or better and give you a little more flexibility in terms of training, maintaining veg, taking clones, and reflowering, but you certainly could use one.
For a pure indica, I'm particularly partial to Williams Wonder (grow report in my signature) because its short and stocky with high yield, high potency, and relatively good scent/flavor. It responds well to minimal training and is easy to clone. Most plants will finish in 64-68 days, and the plant barely doubles in height from the beginning to end of flower.
AK47 is a good choice (though high odor). Mazar mentioned above could work. Afghan #1 and Hindu-Kush are two other really old school classic indicas that are easy to grow.
