Re: “For that verse in its temporal context to denote the entire planet instead is unlikely.”
I’m afraid I must disagree. The entire context of Psalm 33 is looking at all the peoples and nations of all the earth. For example, in verse 5 - “the earth is full of His unfailing love”, vs 8 - “let all the earth fear the Lord”, vs 10 “the Lord foils the plans of the nations”, vs 12 - “Blessed is the nation whose God is the Lord”.
God doesn’t show love to Israel alone, it is not just Israel that is to fear the Lord, rather “all the earth” should also. The Lord foils the plans of “nations”. It is not just Israel that would be blessed by making God their God, but ANY nation that did so. That is the message of the Psalm. God is God over all the earth, not just Israel.
So, I still believe when it says that God has made the hearts of all - it really means ALL peoples everywhere in all the earth.
I suggest spending more time with the Hebrew.

No, He teaches Israel to be the light that draws the world to Him, just as he gave that job later on to a single man in our Messiah. The whole teaching of the Torah is man turning to G_d in repentance, obediently taking a task in faith, surviving His cleansing of sin when he withdraws His protection, sheltered in His atonement, by which to be forgiven and receive the Blessing anew... of which the first example was Noach. Hence, it was Christ's teaching too. Similarly, the people of the Nations were to join Israel freely, from what I can discern, leaving their kings behind. It meant to be a revolutionary teaching from the start. There really is a difference between Israel and the world. Sorry, I don't have time for more discussion on the matter.
