Does doing a
SELECT * FROM (SELECT foo.id, bar.name FROM foo LEFT JOIN bar ON bar.foo_id = foo.id)
\--------------- Will this be a temp table? --------------------------/
create the same type of temporary table as declaring a table with # does in a stored procedure? Or does it create a view or perhaps some other magic?

it does yes, but internally only.
you wouldn’t have access to it after the whole query is executed.
