„Free“ category stock for commercial use in client project?

Hello there.

I am a freelance designer and am currently editing and designing a social media reel for one of my clients (jewelry manufacturer) to promote their jewelry. May I use material from Adobe Stock „Free“ category for the video.

Can you please tell me which license type this “Free” material is subject to? Is this the same as a “Standard License” with the same features? And is this sufficient for the above purpose? 

Thank you!
