Looks like there is no hooks or eventDispatcher to change the data write into the table: webform_submission_log.

So what's the best practise? using hook_entity_CRUD?

In my scenario, I want to log the info like this:

{FIELD1} change FROM {A} to {B}
{FIELD2} change FROM {1} to {2}

Any advice will be appreciated

You should look into this module for token support.

The patch make sense and should have no risk to merge.
