Is there a way to catch both exceptions and only set WebId = Guid.Empty once? The given example is rather simple, as it's only a GUID, but imagine code where you modify an object multiple times, and if one of the manipulations fails as expected, you want to "reset" the object. However, if there is an unexpected exception, I still want to throw that higher.

In these languages, catch will handle those non-CLS exceptions, but catch (Exception ...
One related and confusing thing to know is that in a try- [catch]-finally structure, a finally block may throw an exception and if so, any exception thrown by the try or catch block is lost. That can be confusing the first time you see it.

However, if the TRY CATCH block does, for example, a RETURN (which sounds like a bad idea), if there were a FINALLY block, it would get executed, but with the "final" code placed after the TRY / CATCH, as T-SQL requires, should those code blocks cause the execution to end, that final code won't be called, potentially leaving an inconsistent state.
