MB CPO Extension vs Extended Limited Warranty


I bought a 2020 E350 with 27K miles. It is in excellent condition with CPO.
The new car warranty ends in July 2024, and my CPO ends in July 2025.
So, what are my warranty extension choices?
In terms of extension, can I get the Mercedes ELW since the new car warranty has two more years left? or is it going to be CPO only?
If so, when will be the last eligible date to purchase the extension? is it even worth it? What is the difference in coverage between CPO and ELW?
Thanks in advance.
