If you are already using AWS, AWS Glue is a good option as a catalog type. However, if you want to adhere to the open standards, you may consider Apache Hive. When you plan to use both Iceberg and Delta Lakes and multi clouds such as AWS, Azure, and Google Cloud, consider Unity catalog.
All three catalog types - Glue, Hive, and Unity support Iceberg read and write capabilities. Glue and Unity catalog types support Delta read and write capabilities.
