Well, I'm just starting so for basic grammar and vocabulary Nihongo con Teppei is what I've been listening to, mostly to reinforce and expand upon what I've seen during classes and what I've read from Tae Kim's grammar guide.
I would say he makes for decent listening because he is native, but he can get a bit chaotic later on as he corrects himself mid sentence.
For streams so far it's been mostly Japanese vtubers who speak slow enough to sort of understand what they are talking about, but that has been mostly to train listening and pay attention to the pronunciation and cadence of words when a native speaks. I'm nowhere near understanding many of their sentences due to a ton of missing vocabulary. They act more as a benchmark of progress.
I recommend picking any that talks about topics you understand already, uses standard dialect and does not have a motor mouth. There's enough indies with niche content over there that there is a chance you might find one that appeals to you.
The timezone makes it super rough to catch any livestream so for now looking through archives and finding ones about something you know and find interesting is useful.
