First off, I think the primary objective should be creating value for the company you work for. Bums in seats, lines of code written does not always produce value.
I think any position where you can automate away your daily tasks, and that's an expectation of the job, is great. There is no shortage of companies that maybe run on legacy software that requires a ton of effort to keep things running. You'd be surprised how often companies do things just because that's how they've always done it.
The other great option, which is what I did, is to become an important part of the team, and start negotiating for shorter work weeks.
I think you can find what you're looking for if you combine these strategies, and nobody would fault you on it.
So maybe a good % of the population could be doing more fine without the micro plastics?
