I think the correct way entirely depends on what the person is trying to do and what they want out of the action. I have read that Te-Fi types are "objectivist" and Fe-Ti are "subjectivist".

I partly agree with the above statement. I have a good idea about how something should be done. If something is done incorrectly, I don't really care who did it necessarily, just that it is corrected.
This is just strange, even Ti egos will have a good grasp of Te. Its a fact that there are certain truths about the mechanisms of the world that can't be changed simply by one person's opinion (ex. the 2nd law of thermodynamics). The worst perpetrators of solipsism is LII and IEI. But that's not really what they are talking about.
Something as objectively correct means what exactly? It's a vague and ambiguous statement. A decision, perhaps? Te is an extroverted judging function, decisions based on action in the outside world. Well, time and resources are finite, so there are decisions that optimize the finite resources you have. This would be efficient. Could you cross the Atlantic ocean in a canoe? Possibly, but there are objectively better decisions to make.
