From watching the video of you I would say I, for sure, and P. As far as deciding on N/S or T/F.... I would lean more towards X, and I don't even know on the T/F, I'm inconclusive on that. IXXP? Look into INTP, and INFP, and see if either sound like you. You could be a hybrid. But who am I? I don't even know you.
By the looks of it, you are not an Fe user (Te/Fe are the articulation functions, and you use the former...Fe users articulate more "warmly"), and you are a P, so you must use Fi. You seem to speak with the "grounded" cadences of a Sensor, so I'd say I'd say ISFP.
