Germany job seeker visa question

Hi everyone,
I am applying for a job seeker visa in germany and I have some questions about the requirements.
The checklist has the following:
"CV on ocupational career with certificates and diplomas"
I am assuming that is about professional training, is that correct?
Whom should I direct the motivational letter?
What type of info should I write in the motivational letter? My main motivation is to live closer to my partner's family and my sister as we want to have a baby next year.

Thanks so much,
Ana

Hi,
I have already finished my letter and I would like to share a template.

Date and place
Embassy of the Federal Republic of Germany

Dear Sir or Madam,

-reasons why you want to move to Germany
-family connections in Germany.
-education, professional experience and skills, what you could bring into german society
-if you had already some interviews or your plan to get a job, and type of visa you would apply after getting a job.
-where do you plan to reside and how to sustain yourself during that period.
-if you have kids, where the kids will attend the school and how to make a smoother transition for them.
-steps to fully integrate into german culture (language, cultural events, etc)

Yours faithfully,
