Hi Jess!
Lior from Wix Bookings team.
First of all, thanks for taking the time to write here 
As for the issue you brought up - indeed Bookings form currently doesn’t support all of the field types you’ve mentioned (drop-downs, radio buttons, etc.). A nice workaround we see users implementing is, using CRM Automations, to send user the form via e-mail. Or, as part of Bookings form, you can add a link to an external form and ask the user to confirm she filled the form (see screenshot below).
Please let me know if you have any questions.
