When you say reef safe do you mean won’t eat corals or all inverts because if you don’t want shrimp then that opens up large wrasse and eels (see the description by name lol). For personality no wrasse beats the dragon but it is aggressive. If you want impressive size but peaceful look into Anampses(tamarin) wrasse. For beauty look into the Coris wrasse (note that I mean the genus Coris and there are no such thing as a yellow or green coris wrasse).
For eels you could have any echidna eel or a zebra or a snake eel. All are fairly fish safe.
