As you say, conflict drives the story. So roll with that. It’s personal taste, but I’m partial to soft and fluffy stories where the happy moments are earned.
This may go without saying but longer, more character-driven narratives lend themselves to that sort of development. I love it when the characters we’re focusing on are thrown right into the clutches of conflict. I like seeing them work through it and find a harmony between themselves in doing so, whatever that might look like.
