Given that you're quite early in your career, my opinion is that a certification course might not help as much in festooning the CV. If you want to take it up for learning or still want to have something that you can show on CV, maybe a LinkedIn learning course can be of help. There are many there and you can choose from recruiting to coaching teams to recruitment marketing.
Honestly, at the moment you can consider taking a course for learning and implementing it in your current/upcoming role. The ones that can be expected to add pedigree would be too far fetched for now.
