I think VOY - Counterpoint might fit the bill.

Reasons:

1. It’s got a double double-cross plot with pretty high stakes.
2. It’s traditional in the “alien of the week” format.
3. Janeway and Inspector Kashyk have excellent chemistry
4. Hefty abuse of the pattern buffer
5. Basically a self-contained episode that’s largely confined to the ship
