Well, let's compare them.
The Sports package ships with sport seats (more adjustable, more bolstering and extensible thigh support), sports suspension, 19" wheels, bigger brakes, and the cool front bumper.
Non-sports ships with 17" wheels (upgrade to 19's for $1k), standard brakes and suspension.
For me, I'm big on the bang-for-buck factor, so a non-sports premium with upgrades compares favorably to the sports package. Sport, while having a higher initial cost, also has higher long-term costs associated with the 19" run flats. Under a 3 year lease you will be replacing the tires at least once, and they must be run flats.
If money were no object, it would be a fully loaded, RWD hybrid sports model for me without a second thought. In your case I think a deluxe touring premium model (like mine) is a good fit. Deluxe touring brings some niceties into the mix like the awesome around view camera system, rain-sensing wipers, power tilt and telescope steering wheel, etc.. If you have more than one driver, each driver gets their own set of settings programmed into the key so seat posture, etc. is remembered per person. Without the deluxe touring package, the steering wheel doesn't move out of the way when you get in or out. Being a gigantic driver, my seat is always as far back as possible but the steering wheel will beat on my knees over time, so I need the power steering adjustment. Deluxe touring also gives you adjustable steering. I'm not sure if Sports includes this or not (although I have a feeling it does).
Plus, the maple is just such a nice look. Some people don't like wood, as 15 years of plastic with wood printed on it has left people with a bad impression, but this (as always with Infiniti) is a real wood laminate and has some beautiful depth and character. No two will match due to grain variation. My '04 sedan has the rare birch-like veneer on the doors and shifter, and people always are surprised and compliment it when they see it. Nothing says "luxury" like real wood to me. Aluminum is pretty also but can be found in lots of cheaper models. Wood requires craftsmanship by hand, which gives it a personal touch as well. Any robot can stamp out aluminum panels but wood has to be handled and fitted.
I wish they would have thrown in the adaptive headlights into deluxe touring but they shuffled it into tech for some reason. That's the only thing missing outside of ventilated seats which no models have (yet). We know they're possible since the G37 convertible has offered them for a few years, but they're holding them back. Maybe they don't want to poach already sagging M37 sales.
