I believe that ideally, Jesus wants everyone to receive Him in the Eucharist. The bread and wine are the earthly matter in which He chose to give himself to us, to give us the grace we need to live as Christians.
Unfortunately, not everyone will become Catholic. It is understandable. It can be overwhelming.
It could be that God will meet some people where they are at the moment. Where the Holy Spirit leads some to become Catholic, others are just being led to be the best Christian they can be. Whatever that may mean for them. Maybe later they will feel led to become Catholic. Who knows?
Personally, I believe I had been led to the Church very slowly my whole life, so that by the time I met my future wife, who is Catholic, I was more open to learning more about Catholicism and to converting.
