Get a T12 first. You may need an inductive one for higher wattage in future, buy that when the needs arise as you can a get a better and cheaper one then. There are more portable and battery powered T12 coming out. You can standardise on T12 tips for both the table top and portable irons. For having widest varieties of tip and yet keeping minimum spare, and mostly to keep and to improve your soldering "fu" by sticking to the same type of tip. Original tips are better, you can get best value for lightly used original tips from Japan.
I have an inductive soldering station, never use for my work yet. It is Heavier, so my skill haven't built up, may not have chance to build up. Don't think I can use that to do SMT soldering. I still prefer using 936 tip to do SMT, now slowly able to use T12 to handle SMT.
There are ready made adapters to use your T12 or 936 iron to fit a blade that you can use to cut plastics, or remove adhesive, or fit it with silicone heating pad and use it to reheat the LCD ribbon. Many possibilities, you can do your adapters, it is easier to buy off the shelve.
