Inheritance and type casting problems

I'm in the process of building an inventory system. The inventory will contain a list of slots (also scriptable objects). I have an ItemObject abstract base class, and then multiple derived classes. I'm now wondering if this is a bad design as I foresee long switch statements and type casting in my InventorySlot script when I want to access properties/variables of the item it holds.

I was hoping someone might advise a more flexible solution?

 public class Inventory : MonoBehaviour
 {
 public List<InventorySlot> slots;
 }
 
 public class InventorySlot : ScriptableObject
 {
 public Item item;
 }
