Build a Small SSTO spaceplane that has launch thrusters to get to orbit, pulse drive to quickly travel between planets at FTL speeds, and a hyperdrive which can instantaneously travel between star systems.
It has to look like a No Mans Sky style ship.
You can use cheats like infinite fuel, and you can use mods of course
The pulse drive should allow travel in in-game seconds or minutes, not days or years.
I reccomended some warp drive mods like alcubierre drive warp drive mod. Not sure what mod to use for hyperdrive yet.
