FieldData or Nested optimization - Discuss

Hi guys, I find myself making some changes to an old scrits and I have the doubt that it would be more optimal if I continue using ' fielddata ' or ' nested ' that is to say the scripts do the searches or aggregations from a field like this: "categoryId ":" L: 1001 L: 1016 L: 1023 L: 1029 L: 1036 " so what I want is to establish a ' nested ' to search by ID within it. according to reading 'fielddata' consumes a lot of memory but nested consumes more or is it more optimal at the time of truth?

Example FieldData :

POST listing/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "status": true
          }
        }
      ]
    }
  },
  "post_filter": {
    "bool": {
      "filter": [
        {
          "terms": {
            "categoryId": [
              1
            ]
          }
        }
      ]
    }
  },
  "aggs": {
    "category": {
      "terms": {
        "field": "categoryId"
      }
    }
  },
  "size": 1
}

Example Nested:

POST listing/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "status": true
          }
        }
      ]
    }
  },
  "post_filter": {
    "bool": {
      "must": [
        {
          "nested": {
            "path": "categoryData",
            "query": {
              "bool": {
                "must": [
                  {
                    "terms": {
                      "categoryData.id": [
                        1
                      ]
                    }
                  }
                ]
              }
            }
          }
        }
      ]
    }
  },
  "aggs": {
    "aggsCategory": {
      "nested": {
        "path": "categoryData"
      },
      "aggs": {
        "category": {
          "terms": {
            "field": "categoryData.id",
            "size": 100
          }
        }
      }
    }
  },
  "size": 10
}

Could you share an example of a typical document and the associated current mapping?
