In Ephesians 1, Paul is talking about salvation, and how God chose individuals before creation, not just chose the means of salvation, though that is true too:
“Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, to the praise of the glory of His grace, by which He has made us accepted in the Beloved. In Him we have redemption through His blood, the forgiveness of sins, according to the riches of His grace” (Eph 1:3-7 NKJV)
Words such as "having predestined us to adoption as sons," "He has made us accepted in the Beloved," and "we have redemption through His blood" speak of both the means of salvation and the individuals who are saved.
