I'm looking at it backwards: as an INFP, I love SJs! But I love everybody.
Me and my ISTJ fiancee' get along famously normally; I'm a little tougher than the everyday INFP and she's a little softer than your usual ISTJ, so that might help. She does get pretty frustrated with me if she thinks I'm not on-topic with our conversation, at which point I'll explain that I AM, in fact, on topic because what I was saying is related in this way, because if you look at it in this sense, then they share the same concept and theoretical backing, to which she'll say "What? That's not what we're talking about." Then I sigh.
On the other hand, she sometimes slays me by attempting to recruit or convince me when I disagree, as opposed to just talking about it. When a disagreement comes up, she's employing debate strategies against me, tracing timelines, and dusting for fingerprints to convince me that just agreeing with her makes sense, because her way is clearly more logical, and if I could just see her logic, then I could also be correct and logical! Usually, by the time she's calling her star witness to the stand to testify on her universal rightness, I'm crying and saying "JUST BECAUSE YOU HATE PB&J DOESN'T MEAN I SHOULD, TOO!"
I'm being tongue-in-cheek, but from my extremely INFP vantage point, my feeling is that ISTJs love us! They just wish we could see that what they're saying is the correct thing because it all makes so much sense. Meanwhile, NFs are panicking because we feel like our values/authenticity are under attack. I think that, in my case, I see her as a Death Star, firing at my planet, and she sees me as Chicken Little, screaming that the sky is falling when it's really just her rearranging the clouds.
I have to say, though, that she can really get my ass in gear. I made a schedule yesterday and almost fainted from shock. And I even follow it from time to time! I also don't start to cry about "how the world should be" whenever I read world politics. She has come to really get closer to trusting abstract thought, grey areas in the world, and being able to open up about how she feels. And apparently my value-oriented flakiness is as sexy to her as her logic-oriented organization is to me. And in the end, isn't that all that really matters?
(Sorry, I'm so bored at work it hurts.)
