Just Finished UX/UI Introduction - Where to Go Next

Hello! I just finished the Introduction course to UX/UI, and am curious as to what other learners are approaching next. I feel like I achieved a better understanding of UX/UI, but I want more. Figma came fairly easy since I have a lot of experience in design programs already. (Still much to learn about certain features.)

I am a Graphic Designer currently, I design things like billboards and vehicle wraps. I’m looking to expand my knowledge with a higher paying skillset essentially.

I was looking at the Build a Website with HTML, CSS, and Github Pages skill path.
But also wondering if my time would be better spent somewhere else?
The Full-Stack Engineer career path maybe? Or should I start with “Front” and “Back”?

Thank You for Your Time! Loving Codecademy thus far!
