Hi and welcome to the wonderful world of jdramas!
Now I’m a pretty firm believer that when you’re at a very beginner level, jdrama isn't a very effective study tool. And I’m aware that’s a pretty bold/debatable stance! Obviously it’s great listening practice! And it’s a fun watching hobby! But in terms of your level (N5 working to N4 I’m assuming) and the vocabulary and grammar level of 99% of dramas, watching drama without subs to practice will most likely be more frustrating than its worth. I say this as someone who learned Japanese through consuming Japanese media (In the beginning mostly music)/high school classes/college classes/living in Japan. It's been a lot, and it’s taken about 5 years to get to this level where I can sub dramas myself.
If you're looking for really easy to understand tv (as in, no subtitles needed), I always recommend trying kids cartoons! Maybe they're not as thrilling as dramas, but they’re straightforward and funny with simple plots and an easy to understand level Japanese. Pretty sure I learned more Japanese watching Chibi Maruko-chan than I did watching any drama. Also good are Sazae-san, Doraemon, and Nintama Rantaro!
Keeping this in mind though, I still want to support your love of jdrama!
Here are some popular ones that I've really enjoyed! Hope you will to!
Also movies!
