I absolutely knew even when I left school ("school" school) that none of these would pay, so I assume your question has an implicit "if money was no concern". Because money/job was the reason I picked engineering and CS in college. While I did quite well (academically and professionally), I never loved it. Maybe I liked it here and there. Then I knew this would happen; that's the reason I was at least prudent enough to never do that CS MS (with multiple options for full scholarships in Europe around a decade ago). But not prudent enough to explore masters in many of the non-STEM fields that were there for the taking pretty much. Some of those might have paired well with this STEM bachelors in some way or the other.

I'm still building it out. Going for my Repair Station license next year and hoping to add pitot-static and transponder calibration to my services menu. I wrench on my own plane, but the liability exposure is insane, so I won't sign work for others.

It's really odd, but I think when I disclose this to my tech masters, there is something of a novelty value, and they appreciate that I can sling code... and also other things. That old "well rounded" trope I guess.

Of particular interest was some interesting types of feedback that came from the Tesla coils. Basically we modulated the frequency we drove the coils to produce sound, but the coils would interfere with one another because that’s how electromagnetism works. We had to tune them to different resonant frequencies to play sound. But the interference itself could sound unique and eerie, sometimes like an old-timey radio. It’s similar in principle to a theremin but a very different sound.

Or I could just get a soul sucking job and do this in early retirement. Shrug.

Love the work but hate the pay and toll it took on my body.

Carpentry is fun too but metal is better.

If the answer is yes, I'll stick with software.

When I was in college I did residential landscaping in the summers, and in retrospect it was a good time.

Some of the gears I helped make will still be in use in a century. I find great comfort in that for some reason. The job was rewarding, and interesting, but the pay and commute really sucked.

As for helping others, there were a handful of us in the job shop before it was bought by a bigger machine shop. It's a fairly solitary job.

Maybe a janitor/security job or a bus driver job suits me well. Neither requires a huge amount of training, and neither requires a lot of brain activity so I can preserve my brain cells for hobby programming. Both have a non-trivial number of job openings too, especially for janitors/securities.
