Any Problems with sticking to Japanese Teachers Youtube for a long while?

I'd rank my japanese as n4-n3ish, but I struggle to find things to watch. I really like watching Japanese youtubers who make content for language learners (Like Japanese with Shun). Outside of this, I struggle heavily with other content. Is there any harm in sticking to these kinds of videos for listening comprehension? I know they speak simple and much easier, however that's all I can really handle at the moment and when I go to Japan, I imagine anyone who talks to me will just talk to me like this anyway (tourism). Thanks in advance.
