From where does a necessity come from that the protagonists must have strife, all the time, and at the forefront? Perhaps Voyager is just too subtle for your tastes. Any interpersonal conflict between Maquis and Starfleet would actually end much sooner than it did if it was real life. When a group of people, with different views and methods come together under a command hierarchy, and everyone has a job to do, people will fall into a productive, positive and teamwork oriented faculty.
I'll say it again, This show is not a soap opera. The stories in Voyager are not reliant on interpersonal drama, strife, and angst. The fact that so much is there should be a bonus for you.
From the VOY Bible, the show's premise was to find a way home, explore strange new worlds, seek out technology to get home, merge two groups into a family, and go on adventures. It's a "ship show."
Even though DS9 was also episodic, in many ways it was a space opera. The "Alpha Quadrant" became the local neighborhood. Every season had a bunch of "Kira learns about her past" episodes. Every season had 3 or 4 Ferengi episodes, or O'Brien gets screwed episodes, or Worf is a pariah episodes. BTW, did you know that Worf is a pariah? It's true!
Voyager is not about that. It's about telling compelling science fiction stories, and that is what the focus is on.
