It’s very unpopular among the “cutting edge” Japanese learners on YouTube and forums like these, but I got a LOT of listening comprehension from the 1500 or so hours I spent completely finishing the current Japanese tree on Duolingo. 
Other than that, things that I have found useful are:
Watching content I liked on Netflix with the “Language Learning for Netflix” plug-in on.
My go to stuff is Terrace House and Midnight Diner (深夜食堂). But maybe for some people it is Anime or different kinds of content.
In any case, I switch between really trying to get every single thing that’s being said for periods of time (rewinding, re-reading, repeating what they’re saying, looking up kanji I don’t know) and just letting go for a little bit and enjoying the show with an occasional pause or glance at the Japanese subtitles. I like being able to just be as hard on myself at my current day/mood/lockdown exhaustion allow. And then switching over to lazily enjoying a show I like.
Podcasts: my favourite one is “Let’s talk in Japanese”. I have listened to each of his episodes at least once. In the first episodes, the background piano music keeps going and that gets annoying, but in later episodes he fades it out after the intro. I started out listening to only the ones marked “N4” or “N5” but then after having listened to all of those I moved on to N3 and N2. Turns out being able to understand/follow is more dependant on the subject matter (is it vocabulary I know from Duo or Wanikani) than on the grammar/jlpt level.
Japanese music. I didn’t know any, but through some googling I found a couple of bands that I’m really into. My favourite is Maison Book Club. A weird cross between girl group pop and avant garde modern classical stuff. Right up my alley. But again, to each his own.
Good luck everyone.
