My favorite channel recently is this one. It is all in Japanese and not focused on learners, but for a news channel their speaking pace is actually really good and they cover a wide range of interesting global topics. I would recommend it for anyone around N3 or above that wants to challenge their listening in regard to newscasting without the blazing pace of typical news channels.
In general I find most of the topics they cover quite interesting!
Edit - If you really focus on the audio, you can hear so many of the grammar points that you’ll learn here on Bunpro in crystal clear pronunciation. It’s great if you want to test how well you can piece together sentences on the fly.
