While I can see where you’re coming from, I think that there might be a distinction between a Front/Threat and at least what I think of when I see advice like “prep situations not plots?” The former is a fictional chain of badness, and once written down the principle of “always say what your prep demands” is really “don’t you effing dare pull your punches.”
If you wrote down “Baz’s crew infiltrate town -> the crew roughs people up to figure out wheee the water plant is -> they assault the water plant -> smash it ALL” or some such, each one of those might create situations or places for the characters to intervene or take action. Or maybe they don’t, and you follow through.
And maybe modern situation advice takes inspiration from that sort of thing and I just haven’t read it in detail, but I tend to see or think of it as “stuff for the players to do/explore” vs “stuff to actively impose upon what they care about” if that makes any sense?
To create a story through resolution of a situation you need characters with conflicting wants and ethos. You put the characters together in scenes and see if things change between them and how.
This is the situation in the last game I played in.

King Mirthius does nothing. He is in deep in grief from the hunting death of his oldest son and heir to the Kingdom. He has become withdrawn and listens only to the portents of the sage who predicted his Sons death, the portents he ignored, the portents of…

I've thrown away my notes for this but a quick over view of the first few scenes is as follows:
Scene one: the throne room: all 9 members of the cast are there as the King attends to business. The issue of the plague is brought up and the King consults Leotrix who says that the gods will stop the plague if a great festival is thrown. When talk of an heir comes up he says he is tired and leaves.
Scene two: Theo and Yasmina are in the gardens and she asks him to forget his duties and attend to her. Theo tells her that he won’t do this and being a kings guard is a serious business.
Scene three: Samantha speaks privately with the king and tells him point blank he has to do something about the plague. The king says he will not ignore the portents of Leotrix.
Scene four: Thomas frets about whether Yasmina and Paulus will marry. Sierra tells him he must get Leotrix on their side, using whatever means he feels are necessary.
Scene five: Renald is disappointed the King left before he got a chance to play. Yasmina says she will arrange it so he gets to play at the height of the festival before all the nobility.
Scene six: Samantha goes behind the Kings back, into the city, and starts ordering the plague doctors and wardens to demarcate stuff (basically deal with the plague)
Scene seven: Paulus and Thomas discuss what to do about Leotrix.
Scene eight: Paulus and Thomas basically ambush Leotrix in his room. Call him a fraud, which he denies. Intimidate him a bit, he breaks. They make a deal that they’ll pay him very well and create a way out for him to go and live a life of luxury elsewhere. He just has to say some things to the King.
Overall it was about 70 scenes over two sessions. Some stuff that happened, Theodore gets murdered by a demon summoned by Sierra. Samantha deals with the plague and arrests Paulus and Thomas. Sierra flees. Samantha has saved the day but is exiled because she disobeyed the Kings orders, she goes off to who knows where with Renald (now a poet), hoping to document her deeds. Yasmina and Mirthius, both wrecked by guilt have a huge argument where they accuse the other of putting their emotions above the good of the kingdom. They both accept they're doing that and decide to get on with it.
