Due to the size of the crack a mechanical repair would be best like the aforementioned butterfly or stitch inlay or in lieu of that an epoxy would work. I wouldn't try to color match with dust or pigment as it just plain won't match and may just become an eye sore. If you want to color it go with black or some sort of metallic mix. CA glue, aka super glue, probably won't work here - it's too large of a crack. I wouldn't do it on my bowl. Filling it with gap filling or thick CA will probably result in a mess, also CA glue is brittle while epoxy can flex a little bit with seasonal movement. I use CA glue for hairline cracks, not open, through cracks. And you would never clamp this back into place - there is a reason it split in the first place so don't force it back. (Shrinkage, seasonal movement, too close to pith, internal stresses, etc)
For the epoxy generally almost any two part epoxy would do. Using blue tape, tape off one side of the crack so it doesn't just spill out all over. and fill. After dry remove tape and sand bowl or at least the local area and refinish with mineral oil, wax or a combo of those or walnut oil. Boom you're done.
