Are there any Ghost of Tsushima Missable Quests?

There are no missable items as well for Collections.
If you are planning to play the game only for the story, it's a good approach to do the quests as well for the major characters like Sensei Ishikawa, Lady Masako, Yuna, and Norio.
You can play a few of the Mythical Tales as some of them are the best in the game.
