There's really no reason I can think of that the Dems would deem the Freedom of Choice Act "not a priority" other to play political games in future presidential races. I'm convinced they basically wanted to be able to continue to use the threat of a Roe overturn to steer swing voters to their side, but never actually believed it would happen.
That said, I highly doubt Loving would ever be overturned. It sits on very solid legal ground, and the most conservative judge on the court is in an interracial marriage. Obergefell is genuinely at risk though.
