The Epstein drive is a 'magically easy' source of thrust and delta-V. As such, things like a gravity assist or Hohmann transfer orbit are a thing in the Expanse universe, but navigators can use power to avoid slower, more efficient solutions. I don't recall if maneuvering around the sun ever became an issue, but doing that with the gas giants in the outer system and their moons was mentioned around book 2.

There were off-hand comments of ships aiming to where a station or planet was going to be when they arrive, which acknowledges that it wasn't fast enough to go straight-line aim-for-the-planet.
