IEnumerator Post(string url, string bodyJsonString)
    {
        var request = new UnityWebRequest(url, "POST");
        byte[] bodyRaw = Encoding.UTF8.GetBytes(bodyJsonString);
        request.uploadHandler = (UploadHandler) new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = (DownloadHandler) new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");
 
        yield return request.Send();
 
        Debug.Log("Status Code: " + request.responseCode);
    }

 

Oddly Unity has two different ways? I found that this version they supply works?

Yes, there are two ways:
UnityWebRequest.Post(url, form);
and
new UnityWebRequest(url, "POST");
