If you speak German and want to learn about AI, I think the KI-Campus is the top choice. It mainly offers content in German, and what's special is that much of it comes directly from German universities! The KI-Campus has free online courses, videos, podcasts, and tools to improve your AI skills. Too bad I didn't find it sooner.

PMI is my personal highlight! They offer some excellent free and affordable courses that are both engaging and valuable.

Coursera offers good courses, but the most interesting ones are only available through the subscription model, Coursera Plus. I believe the subscription is only worthwhile if you commit to the annual plan and have the time to make full use of it. Otherwise, you may feel pressured to complete courses as quickly as possible to minimize costs, which can be detrimental to the learning experience.
