should I prefer a sealed interface over a sealed class if possible? or is there no particular reason to choose either, when multiple interfaces are not going to be implemented?

[Kirill Grouchnikov]

General preference in OOP is to code to interfaces and not to classes. What is “multiple interfaces are not going to be implemented”?

sealed interface.
Common scanty is to use sealed interface to define a "base" state and then used data classes and data objects to extend this interface
