The most important thing to do in order to future proof a series is to get the series made in the first place. That means keeping the budget under control so the show can make money with a limited audience now. Most likely that will mean no added cost. Shoot digital in HD resolution. Render all CGI in HD without spending the time to create a more detailed model that you won't be able to notice.
100 episodes in HD is a lot more future proof than 13 episodes in 3D at 4K.
