Limiting to top 30 programming languages based on a particular ranking can be biased and misleading. For January 2024 D TIOBE ranking is 21, just outside Top 20 while your top 6 choice of Julia is outside top 30 at rank 33 [1]. D also support scripting and REPL feature as Julia, but D is much faster at them in which faster feedback is very important for new learners.

For proper pedagogical approach we should refer to the experts and educators. There is one paper from Monash University that have come up with major sins of introductory programming languages that are not suitable for new learners including Pascal that you used during your teaching time. I have provided the link to the paper in my other comment.
