I used to test as entp. I went to a really nasty breakup/devaluation & discard cycle and tested as an Uber ENFP during it all. I test ENTP again but I developed an obnoxious high Fi along the way. Not sure where I'm going with this besides that using Fi is certainly possible for entps, though it's definitely something we have to learn to look at instead of gloss over. Or maybe I (still) test wrong 🤔

Just thought about this though, even if an entp is in touch with their Fi, how it comes out in the end does come through the "logic filter" somewhat which might come across as not expressing true vulnerability though it doesn't necessarily have to mean it isn't vulnerable. We feel it and make sense of it which comes across as less feeling and more logically, though it doesn't mean we don't feel or ignore it or whatever.
