In terms of "strategy", it all depends. If you don't really care where you stay and are just happy to be in a deluxe onsite, then SSR is really the best value. If you always stay at a certain resort and you cannot fathom being happy unless you stay at that resort, then you really should buy at that resort.
IMO, buying GFV points really only makes sense if you intend to use those points exclusively at that resort. Otherwise at 7 months a GFV point is worth the same as an SSR point in terms of booking so paying for that premium is worthless.
Another option would be renting out your OKW points for extra cash and then renting GFV points for yourself if you really wanted to get in periodically. But if your heart is set on staying at the GFV time after time then it would make sense to buy at the GFV.
My advice is to read as much as you can before you buy. Don't make an impulse decision based on a magical week at Disney. Don't stretch yourself beyond your means financially. Buying DVC will likely mean taking more Disney vacations than you otherwise would have if you didn't buy DVC. So factor in whether or not you can see yourself vacationing at Disney year after year after year.
