I've created a Text node, as follows:

Text text = new Text();

I then bind its xProperty(), yProperty(), translateXProperty(), and translateYProperty() to achieve centering, as follows:

text.xProperty().bind(scene.widthProperty().divide(2));
text.yProperty().bind(scene.heightProperty().divide(2));
text.translateXProperty().bind(new SimpleDoubleProperty(-text.layoutBoundsProperty().get().getWidth()/2));
text.translateYProperty().bind(new SimpleDoubleProperty(-text.layoutBoundsProperty().get().getHeight()/2));

Finally, I set the text origin, a font, and the text, as follows:

text.setTextOrigin(VPos.TOP);
text.setFont(new Font("Arial BOLD", 14));
text.setText("Center Text");

I've noticed that the text is not horizontally centered. However, the left edge of the text is located at the center of the scene. If I move the setFont() and setText() calls to before text.xProperty(), the text is horizontally centered.

I'm not sure if I've done something wrong or if this is a bug. Here is a short program to demonstrate:

import javafx.application.Application;

import javafx.beans.property.SimpleDoubleProperty;

import javafx.geometry.VPos;

import javafx.scene.Group;
import javafx.scene.Scene;

import javafx.scene.shape.Circle;

import javafx.scene.text.Font;
import javafx.scene.text.Text;

import javafx.stage.Stage;

public class Center extends Application
{
   @Override
   public void start(Stage primaryStage)
   {
      primaryStage.setTitle("Center Text");
      primaryStage.setWidth(250);
      primaryStage.setHeight(250);

      Group root = new Group();
      Scene scene = new Scene(root);

      Text text = new Text();
// text.setFont(new Font("Arial BOLD", 14));
// text.setText("Center Text");
      text.xProperty().bind(scene.widthProperty().divide(2));
      text.yProperty().bind(scene.heightProperty().divide(2));
      text.translateXProperty().bind(new SimpleDoubleProperty(-text.layoutBoundsProperty().get().getWidth()/2));
      text.translateYProperty().bind(new SimpleDoubleProperty(-text.layoutBoundsProperty().get().getHeight()/2));
      text.setTextOrigin(VPos.TOP);
// Comment out the following two lines when uncommenting the previous commented-out lines.
      text.setFont(new Font("Arial BOLD", 14));
      text.setText("Center Text");

      root.getChildren().add(text);

      primaryStage.setScene(scene);
      primaryStage.show();
   }
}

The program is currently set up so you should not see horizontal centering.
