Helpers are super useful for customization, and they deserve a better GUI and place in Automations.
They should be more like Devices (regarding their ease of use in automations), where you have all the possible values of the Helper in a dropdown.
The ideal is that all the Helpers will just be part of the devices list,
And if you want to control an input_boolean helper then you will have the options of “Turn On”, "Turn Off’, “Toggle” from the dropdown.
And for controlling an input_option then you will have all the possible options in a dropdown.
