Best way to show variable values on UI

Couple options though don't know that any are really ideal. This is one of the issues I have on a regular basis.
- Could create a prefab with the options set
- Could add a menu item that creates the player and sets any defaults you want. https://docs.unity3d.com/ScriptReference/MenuItem.html
- On the menu item above, you could also create a custom asset in a scriptable object to store the player data for that instance.

It would be cool if you could select assets from multiple folders in Unity and then drag them over all at once, having it apply them to the object in the order you clicked them.

Code example for one of my use cases. Has some of methods 2 and 3 in it.

 public class TerrainMenu : MonoBehaviour
 {
     // Put the item under the existing GameObject/3D Object menu
     [MenuItem("GameObject/3D Object/RTS Terrain")]
     static void CreateTerrain()
     {
          // ----- Creating a GameObject in the scene ------ //
          GameObject _terrain = new GameObject();
         _terrain.tag = "Terrain";
         _terrain.layer = LayerMask.NameToLayer("Terrain");
         _terrain.name = "Terrain";
         GameObjectUtility.EnsureUniqueNameForSibling(_terrain);

         // ----- Creating a custom asset and saving it to a file ----- //
         // TerrainData inherits from ScriptableObject
         TerrainData _terrainData = TerrainData.CreateInstance<TerrainData>();
         // Can call any other setup functions you need or set defaults on the scriptable object
         _terrainData.Initialize();
         // Save to a file
         string filePath = AssetDatabase.GenerateUniqueAssetPath("Assets/terraindata.rtsterraindata.asset");
         AssetDatabase.CreateAsset(_terrainData, filePath);
         // My heightmap is a texture2D so I need to save it separately. Still figuring out how this works.
         AssetDatabase.AddObjectToAsset(_terrainData.heightMap, filePath);
 
         // I need to add the script I made to the game object (in your case it would be your player script).
         RTSTerrain _script = _terrain.AddComponent<RTSTerrain>();
         // Finally I need to tell the script about my asset.
         _script.terrainData = AssetDatabase.LoadAssetAtPath<TerrainData>(filePath);
     }
 }
