UUID7 offers several key advantages:

  - sortable by insertion
  - less vulnerable to sequence prediction attack
  - allows partitioning of tables in the future

Sequence prediction attack is a problem when you want to use identifiers in a public API. For example, a user or competitor can iterate through your product catalogue by incrementing the key. Sorting by inserting is a common use case as well. You can achieve this with an auto-incrementing primary key, however, this will create issues when you need to partition the table. Of course, you may never need this functionality, but there is a reason UUID7 have been added, as they are very useful in certain scenarios.
