You only need a G1 overcharged 2A power plant to run everything on the ship (including the cargo hatch), so you can save on mats (and credits, and mass, and get a lower resting heat). You can also downsize the fuel tank to a size 4 (as per Lucifera Danzig's build) to get better jump range on a full tank at the cost of lowering your single tank range from 488 ly to 265 ly.
As for what I use, I use a stripped out hauler with a 59 ly jump range (261 ly on a full tank) and a 13.5k CR rebuy. It can get me just about anywhere in the bubble in 5-6 jumps, and costs peanuts to transfer to my current location. https://s.orbis.zone/40zo
On a side note, I'm currently out of the bubble and scheduled to make a stop in Colonia around Christmas. I should check to see how much it costs to transfer my taxi to Colonia
