Here are some places to start looking for exhibitions:
Local lists and organizations

https://torpedofactory.org/call-for-entries/
https://washingtonsculptors.org/calls-for-entry/
College Art Association is a good resource
https://collegeart.org/jobs-and-opportunities/opportunities/
These are some of the many websites that list calls, mostly non-vetted.

https://artrubicon.com/category/calls/
https://resartis.org/open-calls/

I like finding smallish arts organizations like these, they are usually good places to have shows.
