Six Sigma Certification Recommendations

Hello-

I've been a supply chain professional for about 15 years, but I recently left my role as a Sourcing Manager at a Fortune 500 company in order to take some time off and focus on some personal projects. I began my job-search after the holidays, and I'm considering using my spare time to pursue Six Sigma certification. I'm generally familiar with the principles and program, but I've never actually take the steps to get a white/yellow/green belt.

After some Googling, this program seems promising: https://www.sixsigmaonline.org/lean-six-sigma-certification/

I wanted to ask if anyone who has experience pursuing Six Sigma certification has any thoughts or recommendations to which programs are better, what to watch out for when selecting a program, any other tips, etc.

I'll also note I'm fairly new to professional certifications in general, so pardon my ignorance as I learn more.
