A taxonomy custom field type that is not limited to only one taxonomy. For example, it would be nice to have the ability to make the field type a pool of taxonomies vs. just one.
Any current workaround suggestions would be appreciated.
Knowing how the taxonomy field works, there would be some problems in doing this. These have to do with the way that the terms are sorted as well as the ability to load/save terms and to create new terms. None of this would work correctly if you could pick multiple taxonomies.
My suggestion would be to look into using a different field type to accomplish what you want to do. For example, you could build a select field and dynamically populate the choices https://www.advancedcustomfields.com/resources/dynamically-populate-a-select-fields-choices/. There is also the possibility of building a custom field type https://www.advancedcustomfields.com/resources/creating-a-new-field-type/
You could also submit your request here https://support.advancedcustomfields.com/new-ticket/.
Super-late response, but for anyone else checking here: I had this exact same requirement, and someone else has made a plugin for it:

This just adds another ACF field type called Multiple Taxonomies and works pretty much exactly how you’d expect.
