Nick is the lead character on the show. It doesn't matter if he's "passive" or everyone else around him does the most action or generates the most stories. The point is everyone, to varying degrees, revolves around him. It's not about cherry picking certain parts of the show where someone else looked like they were in the forefront because in the end it circles back to him in some form or another.
Juliette wasn't the lead, she was his victimised girlfriend turned to a scorned woman/villain because of him. It's in S5 that she's first independent of him but only superficially because as part of HW, she still had to work with him and wasn't completely free of Nick's shadow. And S6 is a meshing of too many ideas. In 6x11 she claims her independence again but as a combination of Juliette and Eve but her story still revolves around Nick.
I agree with @irukandji it doesn't matter which relationship you choose, it's Nick that's in the driver's seat, not because he's proactive or anything but because that's how it's written. Shows are typically written to cater to the lead more than to anyone else. They will have the other support cast feign independence from the lead but any real independence results in disappearing from the show permanently unless from the very get go the show is written as an ensemble cast like GoT or Westworld where you can have characters driving their own stories without ever interacting with the others.
