What are online courses could you suggest for starting UI/UX design?

Hey there, I am asking for a friend who is interested in transitioning from their career of designing print ads (Photoshop and InDesign) to web design.

I would imagine they would need some courses on responsive design and Figma? But I'll let the people with experience talk if they're here.

Free is preferred but willing to pay if needed! And if you have links or specific online courses you really like and helped you, that would be great!

Thanks in advance!
