You might consider Chechen, machiche, mora, katalox, jobillo and as suggested Bocote (one of my favorites) for darker woods.
Chechen and machiche have got a tight grain with variations in color. The two look almost identical at times though machiche tends to be lighter in color with slightly less color variations. The machiche makes up for this by resembling more of a figured Chechen in pattern.
Katolox is more of an ebony substitute reaching nearly black in some pieces. In lighter pieces it has a deep dark purple color, sometimes with pale streaks. A pleasure to turn and sturdy stuff.
Jobillo and Mora are a little lighter brown and give more of a 2 tone contrast. Both turn quite well, sand, finish and look great.
Bocote is the perfect high contrast, bold in your face example of woodgrain pattern. It is naturally oily, so you tend to get more "sticky" sawdust than the dry ribbons and shavings of other woods. This is normal, but does not prevent it from taking a finish or adhesives. This is one of the first woods I turned and an early favorite.
(Personal opinion) I'm not a fan of CA. Don't get me wrong, I have many bottles, brands and viscosities in the shop. It has its uses and can be invaluable at times. However, I use a polymer clay (won't dry out and get hard and reusable as adhesives won't stick to it) to plug one end of my tubes. I then coat the inside of the blank with 5 minute 2 part epoxy. A thin smear on the tube and rotate in. 3-4 minutes later (just before the epoxy fully sets) I punch out the clay with a pencil or dowell or whatever's laying around. It comes out easy and clean just before the epoxy sets with almost no work to do cleaning up the end or inside the tube. After it sets and you might have a little work to do.
Finish, I don't prefer CA. I'd much rather use Craft Coat, a UV blocking marine boat finish, lacquers, or even epoxy.. but that's just personal opinion.
Ask 5 turners any question on what's best and you'll get no less than 12 opinions. Find what works in your shop. It's trial & error and experimentation that give the best lessons.
