Video editing on YT

I have more than a dozen materials to edit. They are so complex that I want to divide the work into several stages:

1. to the already prepared material, i.e. cut, with the scheme laid out and the shots backed up, I want to add various animations in the indicated places. E.g. Google reviews, a map showing where we are and where we are going, the process we are presenting, and general graphics that will illustrate what the presenter is talking about. Here are examples:

2 Add music and sound effects to the edited material. Your task will be to select music that matches the emotions presented in the material.

3. subtitles - I want the material to include blended subtitles. By this I mean a style where the sentences do not stretch across the screen, but contain 3-4 words at a time. Here is an example:
