• In the map than appears on the screen change the "Default" node appearance (shape, color, text...).

In all next new maps If you whant to change it in all maps you create open the standard mindmap template (it is: <freeplane_dir>/resources/templates/standard-1.6.mm) and change the Default style as in the previous way. Save the template.
