WYSIWYG editor, wizard, or other tool to make form creation easy for non-IT personnel.

JotForm is a WYSIWYG form builder. You can simply add fields by drag and drop.

Reusable form templates with ability to add and/or delete fields on a cloned form. Can "save" progress on a new form and return to “edit” it later.

Forms can be shared as a template or you can simply clone your form to create a copy of it. Our forms are editable regardless if they are cloned or not.

Here's a guide on how to share your form as a template: https://www.jotform.com/help/157-Sharing-a-Form-in-the-Form-Templates-Gallery 

Here's a guide on how to use the templates: https://www.jotform.com/help/106-How-to-Use-the-Form-Templates 

To clone a form, you can simply follow this guide: https://www.jotform.com/help/27-How-to-clone-an-existing-form-from-your-account 

Staff can upload files to a common hosting repository to customize forms.

I am not sure what you meant here. Changes or customization on forms are done in our form builder. 

Can add hidden fields with pre-selected values to individual forms.

Yes, you can set the fields to hidden and set a default values on them. 

Can preview form before publishing.

You can hit the "Preview" button to see the changes on your form. However, we do not have a "Publish" button. Changes on the form are directly displayed on the live form.

Can use a “redirect URL” to route form submissions to a success page (e.g. PDF).

Yes, you can redirect the user on a different "Thank You" message or a different URL after they hit the submit button. Here's the general guide about it: https://www.jotform.com/help/211-Setting-Up-the-Thank-You-Page 

Can test downloading the success page prior to publishing.

I'm not sure if I understood your concern here. Forms are hosted in our end.

Can deploy an HTML “thank you” prior to the success page.

If you want to have a redirect page, that is possible. Here's a guide that you can refer to: https://www.jotform.com/help/89-Create-a-Custom-Thank-you-page-with-Auto-redirect 

Can trigger form sends from Salesforce events (e.g. customer satisfaction survey) Role-based access control (i.e. can define role permissions, user roles, etc.)

I am not sure what you meant here. We have an integration to Salesforce, but that simply passes the submission data to Salesforce. Here's a guide about it: https://www.jotform.com/help/321-Mastering-SalesForce-with-JotForm 

I hope that helps.
