Question Do you know of a ScriptableObject framework that can use components?

I'm not sure if this is what you mean, but one way to deal with ScriptableObjects in ECS is to convert their contents to a blobasset:

• Make your ScriptableObject just contain a [System.Serializable] struct, and that struct is what contains the actual unmanaged data.
• Create authorings that have a field where you can assign that ScriptableObject.
• During baking, take the "data" struct of the ScriptableObject and put it into a blob asset. Store the BlobAssetReference in a component on the entity.
• Don't forget to make the baker depend on that scriptable object, so baking is re-triggered when the SO changes (in baker: "DependsOn(authoring.MyScriptableObject);").
