If you don't mind spending a few dollars on a book, this might be about what you are looking for?
I know it's not on your list but I really like Tuttle's "Essential Korean Vocabulary".
It's organized into 30-some chapters, thematically, and has over 8,000 words and idioms. It also ranks them all on frequency from 0 (not often used in daily conversation) to 3 (absolutely essential).
Lots of example sentences too that show the words in use, especially with regards to collocations (meaning, words that appear together as a phrase super often).
E: took a photo of a random page from the book: https://imgur.com/gallery/BlrTI
Think I found what you´re looking for while looking for something else. 30 plus themes, romanized pronunciation, example sentences.
