Sorry you and your daughter has such a stressful time around her college decision. Sounds like other people didn't make that any easier (regardless of their intent). I've certainly seen that when someone is deciding on colleges, many adults feel free to dispense lots of (contradictory) advice.
However, it makes sense that the combination of Ni and Fe would be likely to lead to seeing social patterns clearly and letting judgments arising from that clarity be known. Extraverted judging is more externally directed and visible than introverted feeling. All that doesn't mean that if one feels that giving advice isn't appropriate to a situation one can't (or won't) refrain, regardless of type.
I do think our trying to escape emotional upset of others can lead to a certain kind of selfishness in which we want to make the other person happy in order to not have to suffer the negative emotion along with them. That's one way in which practical sympathy is superior to entering into the emotional state of the other person (as we perceive it).
Most of us aren't good at receiving advice (we tend to find it insulting, since we've likely already spent a lot of time mulling over our issue) and tend to give advice more on the order of teasing out how the other person feels. Usually I feel like the other person has really already decided on some level, and I'm just helping them clarify their motivation a bit.
I can see how if one saw advice as bad, having advice associated with one's type would be irritating. Sorry for hitting a nerve!
Edit: The last time I talked to my INFJ best friend from college, he apologized for having been so cavalier with advice when he was younger (we're both early 40s). Maybe it's a characteristic that gets tempered with age and experience, too.
