Firebase Realtime Database accept queries with strings in case sensitive manner.
Does this still apply for Firestore?

Yes, queries are still case sensitive.
To support case-insensitive or any other canonicalization you'll need to write a separate field that contains the canonicalized version and query against that. For example
db.collection("users").where("name", "==", "Dan")
db.collection("users").where("name_lowercase", "==", "dan")
