I watched rosario vampire, angel beats, highschool of the dead, persona 4, dbz, naruto, hajime no ippo, and my hero academia

Depends on what kind of anime you like. My favorite is probably samurai champloo!

honestly, just watch things that are completely different to what you've seen already, you've barely watched anything yet so it's best to just try to broaden your scope and just try a lot of different stuff now, you've mainly watched shounen with some very slight romance, so maybe watch some mistery like ghost in the shell (+ stand alone complex), some drama like revue starlight or some slice of life like yuru camp. Just try to watch things that you currently don't have any frame of reference for.

From the top of my head...

Sakamoto days
The Fable
Bleach (4th season coming this year so maybe catch up?)
Girls band cry
Ranma 1/2

Ghost in the Shell: Stand Alone Complex. Watch should probably watch the movie first but it isn't necessary. There is also a bunch of different spin-offs and sequels to the movie, all pretty good.
