Big caveat: I don't know much about your position or where you're located. Sometimes that matters; Cobol, Fortran, Ada, Perl, etc are still around but job opportunities vary. If I had to guess, places that use them are less likely to offer remote working soon. Also, nobody can predict the future. How longer shelf-life do you need? 10 years? 20 years? You might've moved to e.g. product or program management by then. I want an easy life, too, and don't plan on sticking to programming the whole time. I figure I'll know more in ~10-15 years. Anyway... Ruby on Rails is still well and alive (see Ruby 3.0, and the recent mimemagic issue), overall I think PHP is more widely deployed (and alive, see the recent malicious commits to PHP. worth exploiting like that = people use it and update it). As brundolf said, Wordpress is everywhere. You could go off the one you prefer more, but I'd definitely recommend reaching out to contacts and just casually surveying if they know what places use what to give you an idea of your local situation.
