Suggestions on Salesforce to S3 migration.

I am performing data migration from Salesforce to S3. So I am using Glue Zero ETL service for the same. We were able to get most of the objects to S3 using zero ETL but there are some standard objects within Salesforce which zero ETL does not support. So how should we resolve that.

1. One approach we thought is : Copying standard objects data to custom object and then pulling that object. This way full load is done and for cdc of that object we will turn Apex Trigger + Queueable. But is this right approach? Because it's another type of migration and we will again migrate this to S3. Need suggestions on this.
