I haven't watch Zombie Detective and Midnight Studio but:
Enigma, Oh No! Here Comes Trouble, Pee Mak, and Till We Meet Again have ghosts and comedic element so it's quite similar to Hotel Del Luna. But Enigma is more serious than the others.
I am Nobody and Tale of Nine Tailed 1938 have similar comedy style and sad background stories as Goblin
Oh! My Emperor, Rooftop Prince, Splash Splash Love and The Romance between Tiger and Rose have some similarity with Mr. Queen. But in Rooftop Prince, ml and his group of friend transmigrating into modern life.
I already delete some of dramas you've watched.
