If for example, your class uses a database, the destructor would be a good place to close the connection.

Yup, but DBI connections already come with a destructor that closes the connection, so :)

Another use scenario is to break circular references, but those are easily avoided with https://metacpan.org/pod/Scalar::Util#weaken

Yup, in perl, I've rarely written a destructor
