New to Development: request to kindly advise foundational and beginning study topics (from the below list)

Although alittle later than most, I am determined that I would like to greatly expand my understanding of development. With this, I recently purchased a development bundle to help kick-start my journey. There is such a wealth of information available that I am not so concerned with finding reference materials, but rather my question pertains to which topics/programming languages/etc. are perhaps considered easier for a beginner…

**Can anyone kindly advise which of the below, or perhaps suggest another topic, to kick-off a self-paced development study? (I know formal training and education is normally recommended/required, but I just trying to expand my personal understanding and not actually trying to move into a new career – we shall see…)

Below are the topics which I have placed into my “foundational” bucket… (My end-game is to be able to actually use the Mac development tools).
