Answer 1

Making your site dynamic have a lot of options within WordPress. 
 

1. Via Custom Meta Boxes
2. Via Customizer API
3. Via Widgets

The above things have very good documentation on WP Codex. Of course, if you wish to simplify those things, you can use existing plugins such as Advanced Custom Fields (ACF) and/or some Page Builders like Beaver/Elementor. It all depends on how much you wish to work on your site and how clean and specific your approach you wish to be that is directly influenced by how well you are versed with WordPress development.
