The most future proof is the least proprietary. You mentioned future proof though as being in one year. What is going to happen in one year that your bike is suddenly outdated or inadequate? It will work in one year as it works now. It's not like this is the mid 90's and you are buying a computer....
You can still buy bulletproof 3x square taper cranks and a BB that will survive a sizable nuclear yield for under $60.
