Review order changes the feel of your session.
In general, Due Date (Reviewed First) is the normal default and the generally preferred mode. New users start there, and that makes sense because it usually gives the best balance between urgency and flow: reviewed cards come first, then the rest continue by due date.
The other modes are still useful. A more grouped mode can make review feel more locally coherent when you want to stay inside one surah's flow. A type-grouped mode can help when you want clearer separation between part maps, surah maps, and verse work.
So the best way to think about it is simple: stay on Due Date (Reviewed First) unless you are feeling a specific friction that grouped-by-surah or type-grouped order would solve better.
