Try watching some good ones like

Date A Live
Higurashi no Naku Koro ni
One Punch Man
Hunter x hunter death note
These suggestions are surprisingly not so bad... well the later ones.
I think that popular and not too long animes like Demon Slayer, Attack on Titans or HxH are good to start with. And then you can watch some other known animes (Sword Art Online, Fullmetal Alchemist, Death Note, Promised Neverland,...). Before watching all these you will probably have an idea of what kind of anime you like
You have a strange idea of "not too long" when most are only 12-13 episodes.
If you really want to know what kind of anime you like, you shouldn't watch the really popular ones because they are more similar than they are different (mostly fighting featuring guys).
