Use more specific exception types

[lbianchi-lbl]

• The update to Pylint 3.0.3 enabled the broad-exception-raised check
• As part of #1351, I've added Pylint exclusions for existing instances throughout the codebase
• This would be relatively simple to address (no runtime behavior should be affected by changing an Exception to a more specific subclass, so tests or other client code wouldn't necessarily have to be changed)
