Delete object only with standard storage class in S3

I have an S3 bucket containing 7 TB of data, with approximately 6 TB stored in the Standard storage class (around 40 million objects) and the rest in Glacier. I need to delete all objects in the Standard storage class while retaining those in Glacier. Since the objects are randomly distributed within the bucket, there is no specific folder to target for Standard storage class objects, making lifecycle rules unsuitable for this task.

can somebody suggest an efficient and straightforward approach to achieve this?

Thanks!
