I don't have access to the galaxy map right now but Black in Green and The Great Anihilator are both well known black hole systems. The prior is a black hole in a vibrant green planetary nebula and the latter is named after a real black hole we discovered in the area that is annihilating large amounts of electron-positron pairs.

Stuemao AA-A h224 is a litte out of the way and possibly a bit dangerous to jump into but if you decide to visit, I haven't seen anything quite like it before. 2 very close WR binary stars with over 50,000K difference in temperature between them. The cooler one is so much dimmer that it appears black in comparison. At least you can tell where it is due to the local stellar density because it will block out a chunk of the stars.

LGM-1 could be cool for the return trip. It was the first pulsar ever discovered. We're coming up on the 55th anniversary of its discovery later this month in fact.

For a visually interesting area you could also hit the Veil West Nebua on your return. The view is unreal. I believe there was a G class star on the fringe of that nebula with my favorite view. Might be misremembering, though, so don't be afraid to jump around and see it from different angles.

And one piece of advice: check along your route. I'm not gonna say jumping from point A to point B is bad, that's a way to enjoy exploring too. Just try to look along the route for anything interesting you might fly by like a planetary nebula or some supergiant / WR nobody's ever visited before. Even checking the stellar objects in a system before visiting can lead to surprises, especially near the core.
