As others said, the Arch wiki is so well made that it should be the only source you need. Videos will not bring you anything given your background. The main difference with other distros will be the package manager.
A video about the install process will just be someone reading the wiki to you, and a video to “explain” pacman to you will be overkill ;)
Seems outside of what one would expect from a terminal. There’s dedicated app to handle this task.
