Hi Emre,
I would recommend to take a look at the following Analog Design Journal, EMI filter components and their nonidealities for automotive DC/DC regulators. It goes into detail about when selecting a CM choke. Also, I would like to point out that a common-mode choke is optional if other techniques are used. It serves as the last step if high-frequency noise cannot be eliminated. SNVA886 is another great report that goes into detail of different approaches.
Regards,
Alejandro
