Ah, I like this, and can relate. I find my preference is actually to wing it - to read, adjust, play off of whatever is happening in the moment.
When I look at all of the 'big discussions' I have had in the past, like at work for example when I need to bring something up, I have the one or two elements I want to mention but otherwise I have no idea necessarily what I'm going to say to the other person - I just let it come out as it comes out, and ofc their input will create a dynamic element.
As a tangible example, may or may not be tied to Se, I think it may be why I am pretty good at finding my way around, when driving; vs people who get lost even when they have a GPS.

There might be something up ahead, oops, I'll go this way instead even if I've never been on the road before, I have confidence I'll be able to feel my way to where I need to be...
Also, I'm definitely a learning-by-doing person. Just throwing myself in there; this is probably tied to 'I'll know what to do once I get in there' -- vs people who immerse themselves in manuals and reading up on all kinds of things before doing it (I'm reminded of years ago an NFP on here who I chatted with in a thread, where she said in order for her to feel somewhat OK doing something she was nervous about (I think it was tied to an outdoor sport, like whitewater rafting or something like that), she read up on it and learned as much as possible before doing it. vs me, I did the same activity without having read anything and being clueless essentially about what it would be like -- but for me that's the fun of it, learning in the moment, exactly what it's like, vs going in with some set of data that might skew or bias my natural mode/skills of experiencing then and there. I am perhaps the anti-researcher.

There's pluses and minuses of both, certainly.
