I hope to hear actual pilots chiming in, but from first principles:

It shouldn't be a large factor. Drag is independent of mass, and while lifting the fuel to cruising altitude takes energy, most of the flight should ideally be cruising.

The rocket equation doesn't apply; that's for an entirely different regime.

While drag is "independent" of mass, the lift required to maintain level flight is affected by weight, and drag is affected by lift. A heavier airplane will absolutely require more power to cruise.
