The “cake guy” case ended up being decided on case-specific conduct of state officials, not the merits of the law, leaving the fundamental question of the federal constititutional validity of the state law to a future case.

This is (provided no case-specific issue provides an excuse to avoid that issue) potentially that future case.

Also potentially not; the Supreme Court has been deflecting cases raising similar issues since Masterpiece Cakeshop, and I don't see any change (e.g., a conflict between the Circuit Courts on the issue) that would be a strong basis for believing that would change, though its also possible that the number of such cases or change on the Court could be sufficient to motivate taking this case.
