I’m still a relatively new learner, and was in your spot not too long ago. There really isn’t much out there, especially in terms of actual television shows. I found that purpose-made comprehensible Japanese youtube videos were my main source of N5 content, Sounds like you’ve found those, and are looking for passive rather than active listening.
Chi’s Sweet Home is the only one that I ever found that really fit what you’re describing - but I think it might really work for you. It’s on Crunchyroll and has a whole bunch of relatively short episodes. It’s a children’s program (based off the manga - lost kitten finds new home and has adventures), and it’s got very simple dialogue with a lot of “space” between lines.
The other old standby is Shirokuma Cafe (animals in the human world get up to hijinks at Polar Bear’s Cafe. I saw that recommended as an entry-point anime series in a number of places, and I gave it a good run when trying to find N5 video. I personally found it a bit hard to follow at that level, but it is definitely among the more accessible ones - and it happens to be quite entertaining, which is what you want. Kimi ni Todoke (high school slice of life) is in there, too - it was too advanced for me to have a clear understanding of what was going on at N5/early N4, but good for getting the “feel” of the language.
For immersion, I personally found podcasts to work better for me. The absence of visual cues is a real downside. But I think it’s a little easier to find podcast content pitched to the N5 listener than actual television shows. Nihongo con Teppei and Japanese with Shun were the ones I really got into.
Hope that helps!
