I’m a bit confused about the role of indexes in this context. They seem more about performance than availability.

I feel like user roles and storage engines are important, but they don't directly relate to high availability like replication does.

Putting indexes on all documents? That doesn't sound like it would help with availability. I'll rule that one out.

I'm not sure about sharding - that's more for scaling, right? I'll have to double-check the differences between that and replication.
