Edit: Here is my item system so far (I just included MeleeWeapon because I didn't want this to get too long).

public abstract class Item {

    [Header("Basic Info")]
    [SerializeField] private string name = "";
    [SerializeField] private Image icon = null;
    [SerializeField] private GameObject itemPrefab = null; 
    [SerializeField] private float weight = 0;
    [SerializeField] private int maxStack = 0; 
    private Guid gUID;

    public string Name => name;
    public Image Icon => icon;
    public GameObject ItemPrefab => itemPrefab;
    public float Weight => weight;
    public int MaxStack => maxStack;
    public Guid GUID { get { return gUID; } private set { gUID = Guid.NewGuid(); } }
}

public abstract class Weapon : Item {
    public abstract void Attack();
}

[System.Serializable]
public class MeleeWeapon : Weapon {

    [Header("Weapon Attributes")]
    [SerializeField] private MeleeWeaponTypes weaponType = default;
    [SerializeField] private float damage = 0;
    [SerializeField] private float chargeDamage = 0;
    [SerializeField] private float meleeSpeed = 0;
    [SerializeField] private float chargeTime = 0;
    [SerializeField] private float chargeCooldown = 0;

    public MeleeWeaponTypes WeaponType => weaponType;
    public float Damage => damage;
    public float ChargeDamage => chargeDamage;
    public float MeleeSpeed => meleeSpeed;
    public float ChargeTime => chargeTime;
    public float ChargeCooldown => chargeCooldown;

    public override void Attack() {
        // attack
    }
}

I have other stuff in Weapon and its derivatives but I removed it to keep the base idea more simple. Anyway, I then have prefabs with a MonoBehaviour that hold a derived type of Item, like I showed above, as data containers that I use to instantiate items during runtime.

Unity - Change base class variable to a derived class in inspector dynamically

In an item system I'm trying to create I'm using prefabs to store an item's default values, and then grab that item from the prefab to use in runtime. It works well, but I was wondering if there was a way to dynamically change a variable with a base type to a derived type, probably with a custom editor, so that I wouldn't have to make separate classes for each derived type. This is the how I'm imagining it would be like:

public class ItemPrefab : Monobehaviour {
    public ItemTypes itemType;
    public Item item;
}

public enum ItemTypes {
    meleeWeapon,
    rangedWeapon
}

Item is an abstract base class, and MeleeWeapon and RangedWeapon are serializable derivatives. With that, I'm trying to do something to the effect of this:

switch (itemType) {
    case ItemTypes.meleeWeapon:
        item = item as MeleeWeapon;
        break;
    case ItemTypes.rangedWeapon:
        item = item as RangedWeapon;
        break;
}

I was wanting it to be the same as the below, just less scripts.

public class MeleeWeaponItemPrefab : Monobehaviour {
    public MeleeWeapon item;
}

public class RangedWeaponItemPrefab : Monobehaviour {
    public RangedWeapon item;
}
