Career tests-- are they helpful?

What I did was take this class: https://webschedule.smccd.edu/course/202103/40889 . It was free to me through dual enrollment and I bet your local community college has something similar. The school has a subscription to this site: https://roadtripnation.com/edu/ . I explored that site and followed the "roadmap to careers" prompts. I took and received interpretations of my Myers Briggs Type Indicator (MBTI) and Strong Interest Inventory (SII) Career Assessments results. Then I used https://eureka.org/ . I completed the Inner Heroes Assessment on eureka.org. Then completed the Values Driven assessment on eureka.org. Next, I completed the True Colors Assessment on eureka.org. And lastly, completed the MicroSkills Assessment on eureka.org. We also did "family trees" where we listed the known education and employment history of our families. Then I had to interview/job shadow someone in a career I was considering. Then I had to take everything that I learned about myself and my strengths and interests over the semester and write out my college major and career plan. I had to identify my next steps in reaching my goals as well as differentiate goals I'd already had from new goals I'd come across. In the end, I make a LinkedIn account and put it all together to describe what the professor called "superpowers."

I don't know that there was one assessment I found more important than others. Maybe the Strong Interest assessment, because it changed my results the most. I only had results for low-paying careers, like Etsy craft artist, with Myers Briggs. But the Holland Code for my Strong Interest Inventory was AIE. That helped me identify cryptanalysis as a career option and decide to major in mathematics.
