I remember there was one show back in either the later '90s or early '00s that really took this to ridiculous extremes, but I can't remember what it was now.
Fringe had so many cases coincidentally relevant to the characters' lives that they actually lampshaded it in one episode as some kind of cosmic synergy or something.
It was also a staple of Lucifer. That show never explicitly tried to justify it, but since that was a series where God literally existed, I kind of figured that God was influencing events to expose Lucifer to situations that would affect his personal growth.
