It seems an 'angel shot' is the bar shot with two half spheres connected by a bar.
Spider shot is chain shot but with a number of chains.
The destructive force of any sort of cannon shot was unimaginable and horrifying even though low velocity, some moving seemingly slow through the air could have gruesome effect. With that capacity with a simple round shot ball, one can only imagine what these more elaborate devices could do.
Obviously, with chain shot, the bolo effect against a mast or rigging would seem more effective than with a ball with more localized damage on strike. As noted, these were not especially accurate with their erratic aerodynamics, so would only be close range use. The idea was to immobilize the opponent vessel to prevent escape.
In the superb book on piracy by Benerson Little, "The Golden Age of Piracy: The Truth Behind Pirate Myths" (2016), p.101, he cites a reference from "A Relation of Three Years Suffering" (Robert Evard, 1746). In this the authors narrative describes being aboard the English ship Bauden out of London attacked by pirates off the coast of Madagascar in 1686. Apparently the pirates had made several contacts with the ship, but finally in the process of boarding, the author says, "....his SHOT cut many of our shrouds".
While as often the case in recorded accounts, the 'type' of shot used is not specified, however as per our discussions, it would suggest that the type would have been chain shot.
It would seem that pirate vessels would have favored this type of weapon to immobilize the targeted ship to prevent it from escape...without damage that might sink the vessel before thorough plundering.
While not specified in actual accounts, this lack of mention is contrarily well portrayed in the "Pirates of the Caribbean" fiction with Jack Sparrow shouting, "...load your guns with chain shot! Aim for their rigging! We must slow them down". Hooray for Hollywood!
