Hello,
Is this the appropriate use of Custom Taxonomy Fields?
You can use the field taxonomy
of WordPress. It works the same as the Taxonomy meta box of WordPress to set the post terms.
How do I display the data for it using MB Views if so?
Please follow the documentation to use the View template to output the post data and custom fields
https://docs.metabox.io/extensions/mb-views/
How do I display the data for a particular Custom Taxonomy if multiple of that Taxonomy are assigned to a Post?
If you want to display some specific terms in the frontend, you need to create some custom code to do so. If you are not able to complete the task, we offer a customization service with an extra fee. Please contact us here for more details https://metabox.io/contact/
