Once the game is out in its full glory, with a whole wide universe to explore, travel times are going to become a serious consideration, and for the kinds of transport you describe I think you want both a very high quantum speed and range.
You can find these here in a version that will no doubt undergo huge change before implemented. Drag the bar right to see the quantum speed and range of various ships as currently planned:

Note the plan seems to be for long haulers like the Starfarer and Caterpillar to have very fast jumps and able to jump huge distances. The difference in time between fast (133) and slow (39) is more than a factor of three, so for instance where a Caterpiller will take an hour, an Avenger Titan will take more than three hours.
If you used only these criteria, you'd probably want to use something like the Starfarer Gemini for a transport, but of course that would not be practical under many circumstances due to fuel consumption.
If you go to the ship design section at Hardpoint, you'll see that they're already identifying which jump drives will fit in which birds and what their stats are. So for example, for the MISC Razor EX, you can select between about 8 quantum drives with jump rates between 39 and 50 megameters per second, each of which has a different max range and they force you to choose which is more important, speed or range. Also note, the jumps with great stats in speed and range, have crummy stats for a stealth bird, so you probably don't want to choose stealth as a transport option, since that will require more time during and between jumps, or ruin the stealth on your
Sneaky Pete.
Certainly whatever you decide, what you really want will not be stock on the bird you select! That's designed to make all our birds custom and therefor expensive when we get them all blowed up.
Simplest take away is that the bigger birds fly faster in quantum--is very counterintuitive. So you may indeed choose to ferry back and forth in something like a Star G if you can sell fuel on every other hop, or a Cat if you can sell cargo between. Better still is you just don't need to do much empty transport of yourself. The game is designed to make long distance movements laborious, and therefore much more like real travel. Best is always to get paid for your travels. Second best could be waiting to hop a flight on a Star G. Is going to be one of your quickest options it seems.
I think to avoid travel, many players will just choose to have an alt. The game does not forbid this and that is the simplest way to avoid travel--be in more than one place at a time, especially if you are interested in more than one vocation.
