Quality of Microsft's SQL Server Training/Certification
If your company is willing to pay, I would suggest you to have a subscription for Pluralsight. Its worth for your company or as an individual as well its worth taking it.

(I am speaking from my experience, since I have the subscription and its worth quality investment). 

It has courses from SQLSkills team and other people which teaches you a lot about SQLServer - internals, XEvents, Query plans, troubleshooting methodology, powershell, etc.

As a side note, certification will give you a level of confidence to you and your employer, what matters is hands on experience.
