I would say that when exploring the edges of the galaxy you'll need a big jump range build.
The simple reason is, as
@goemon mentioned, in those areas plotting route is the main skill you'll need and the smaller the jump range the more complex, risky, slower, wasteful the routes will be.
So get a highly engineered conda, with the biggest jump range you can (without sacrificing the other resources you'll need) and good luck.
Bringing a standard, low effort, cheap, fat, touristy or cute exploration vessel to this region of the galaxy is foolish, we're talking about extreme distances and conditions, not a walk in the park.
I would recommend 75+ ly jump range for decent mobility in such areas.
