Thank you for your question and sorry for the slow reply. This discussion on the #uswds-public Slack channel contains some useful information.

Here's what one of our developers said on Slack:
USWDS does not offer a tabs component at this time due to research needed surrounding accessibility and hidden content concerns.
We do offer an Accordion component which allows you to condense pages where appropriate.
We do offer dropdowns in the form of a select component, or combobox component depending on your needs!
