Differences between the Ashkenazi and Eastern Jewish versions of prayer

Hello Rabbi,
As a Sephardic religious Zionist, I have been exposed to many differences in the wording of prayers that I would like you to enlighten me about.
In three places in the prayer (as an example), there is a difference between the Sephardic and Ashkenazi versions, which could indicate a different worldview.

1. Blessings of Dawn:
Sephardi – "…and let not the evil inclination rule over us…"
Ashkenazi – "..and let not the evil inclination rule over us…"
2. Love of the world:
Spanish – "…and your love will never depart from him…"
Ashkenazi – "…and do not take your love away from him forever…"
3. We must praise:
Sephardi – "…as it is written in the Torah…"
Ashkenazi – "…as it is written in his Torah…"

From my understanding, it seems that the Ashkenazim place an emphasis on God as the one responsible, the main mover, with less emphasis on the person, compared to the Sephardim who place more emphasis and responsibility on the person.

I would love to know what the perceptions are and what the differences are between the perceptions.
And if the rabbi can, also refer me to books on the Sephardic understanding of the faith.

Thank you very much 🙂
