Help me understand the new world

A few years ago I hit software development hard. I built several projects, learned frameworks, listened to book(s) on testing/clean-coding, etc. The market was tough so I pivoted to sales, however I want to return to engineering. The pervasiveness of Cluster B personalities in the sales industry is draining in a way that I'm not okay with. I want out. \----- It seems like the software-dev world has changed so much that I'm not sure what I **should** be doing to prep for when I send job applications again. I'm close to finishing my BA degrees, and then I'll probably go for the MSSE at WGU. 1) Given the symptoms of my autism and probable ADHD, I would not do well in an office. So I'll be looking for remote roles. Which language(s) should I be learning for my best odds of being hired? Java? 2) Should I study undergrad-level CS concepts in my free time, e.g. DS&A, operating systems, etc.? 3) I haven't used AI to code and I don't know how I should inject AI into my process. Any recommended resources to show me *how* I should be using it?
