The not being open to alternatives is the Ne vulnerable. The particular circumstances you describe sound more like Fi+Ni (making negative character judgments - "I know who you really are") so I'd say ESI > LSI.
Ne Polr would be my guess too if it wasn’t for the EJ temperament.

I realize my OP made them sound neurotic but the person also has many admirable qualities - assertive, extremely hardworking, driven, courageous, loyal, kind, reliable, and if they promise something you can be 120% assured they will deliver. And definitely an extrovert.

I thought about SEE but the person is almost all work and no play and I doubt any EP would be like that. I think 4D Te > 4D Se. Suppose LIE makes the most sense.
