A federal court MIGHT make that determination, should a case properly raising the question come before it. They don't automatically rule on everything the president does, though.
The judicial branch is the main actor that decides whether or not an action of the government is unconstitutional. However, technically the President can decide not to enforce parts of a law Congress passes on the basis of unconstitutionality through constitutional signing statements.

Determining whether the policy is constitutional
"Arising under" refers to a legal concept used to determine whether a case falls within the jurisdiction of federal courts. Specifically, it pertains to cases that involve federal law or constitutional issues, meaning the cause of action originates from federal statutes or treaties. This concept is crucial in establishing whether federal courts have the authority to hear a case, as opposed to state courts. Essentially, if a claim is based on federal law, it is considered to "arise under" that law.
President Thomas Jefferson questioned the constitutional right to purchase the Louisiana Territory.
The president doesn't have the job to "take action " to solve problems. It is up to congress to make laws. He can put pressure on law makers, but he doesn't have the power to make law. Much of what Trump is trying to do with laws today is not constitutional and has gone to the federal courts because of it. A president is not a king and can't make laws.
formulating the initial idea for the policy
The federal courts have been called "the guardians of the Consistution" because they judge whether laws and action conform to constitutional principles. However, a court may address a legal issue only if a relevant case comes before it. It cannot try to solve legal problems on its own.

he promised federal funding for school desegregation
When President Dwight D. Eisenhower sent federal troops to Little Rock, Arkansas, during the 1957 school integration crisis, he was exercising his constitutional power as Commander in Chief of the Armed Forces. This action was taken to enforce federal law and ensure the protection of the Little Rock Nine, a group of African American students attempting to integrate Central High School. Eisenhower's intervention highlighted the federal government's role in upholding civil rights and maintaining order in the face of state resistance to desegregation.
