I know that Batuu is said to be the last settled world before Wild Space but has it ever been identified in Legends OR canon, the last settled planet at the very edge of the galaxy; right before the Intergalactic Void?

In Legends there are settled worlds in the first two of the seven satellite galaxies of the main Star Wars galaxy. If we are excluding those worlds you're likely looking at Kamino (which sits alone in the Intergalactic Void between the galaxy and the Rishi Maze [aka Companion Aurek] which is the first of the seven satellite galaxies. If we're talking exclusively inside the main galaxy you have a choice of a myriad of remote worlds such as Belkadan and the planets of the Kathol Sector . It also depends on what you mean by civilized.

Yeah, I don't think there's ever been a "last gas till you discover an uncharted other galaxy" sign.

If anything Star Wars has a bad habit of placing something just over the next hill.

Juice provided a great example with the Kathol Sector. Gandle Ott is the last civilized planet that's formally a member of the galactic government, but the rest of the sector isn't anarchy. There's independent planets, small alliances, local intersystem governments all they way out to the rift. And if you follow the Darkstryder campaign, you'll come out the other side of the rift and there's stuff there.

So it's probably safe to say that Batuu is the Gandle Ott of it's part of the Galaxy. The last place where you can be sure to find stormtroopers, republic/rebel/resistance, Hutt goons, and the like. After that it's the wild wild west. You still can come across stormtroopers out past Batuu, but they'll be on thier own, conducting some deep space special mission or something, and the real authority will likely be some local government that doesn't give a poop about the Empire/New Order/Alliance/Republic/Resistance beyond it's extremely limited local impact.

I just also don’t get why canon Disney Star Wars is so afraid of intergalactic stuff. Humans (sentient beings) are naturally curious by nature. If they’ve had FTL technology for over 1000 years; I don’t know why they didn’t ever try to leave the galaxy and colonize others. Once the Emperor took over; I would be by Andromeda by 18 BBY.

Well the Galaxy is a big place. The Empire/Republic and it's known territory only covers about half it. Why risk crossing dark space when there's plenty of uncolonized, undiscovered worlds in the Galaxy you are in.

Heck, Ozzle pretty much said so out right in ESB. There's so many uncharted settlements the Empire just doesn't care to track them all down. Pirates, smugglers, religious sects, outlaws, survivalists, frontiersmen, wildcaters, so on.

As for Dis/LFL... Because the Galaxy is the setting. That's the place, it's what the setting is like. It's a galaxy far far away, not several galaxies far far away. Moving to another galaxy would be awkward and unnecessary.

In universe there is a hyperspatial disruption that envelops the galaxy and its two closest satellites, preventing hyperspace travel out of that hyperspatial bubble. Out of universe, it's a conventient hand-wave to prevent the setting from becoming even more unnecessarily large than it already is.
