Are you able to provide one or two motivating use cases? i.e. scenarios in which I would strongly prefer to use this library rather than a std::array and static_cast?

You mean, in addition to https://github.com/julien-Blanc-tgcm/indexed_array#sample-use-cases ? Another benefit that i did not speak of is that you get type safety for the index. i.e. you cannot use a wrongly typed index: indexed_array messages; std::array messages_arr; // ... play_message(messages_arr[static_cast<int>(tech_message::goon)]); // boom at runtime play_message(messages[tech_message::goon]); // fails to compile I also find the code clearer (the static_cast just adds noise in my opinion), but that would be a matter of taste.
