To answer your specific question re: "career prospects/lifestyle of UXR"; I used to do that work full-time, and even founded a consulting business around that. FWIW, I also chaired one of the largest local chapters of the relevant ACM special interest group (SIGCHI). However, I don't work in that field anymore, by choice. And I'm somewhat pessimistic about it, even though I still think it is a critical discipline. My reasons for leaving are:
-- Smaller companies can only afford one person, so they typically hire someone with an art school background; and expect that person to also be able to do UX work well. They are really distinct (but slightly overlapping) skill sets, so it is hard to find one person who is competent at both! Especially on a small company salary...
-- Personal to me: I don't have that art-school background, so that puts me out of contention for a lot of jobs.
-- Most 'tech' companies, from giants like Apple, to small start-ups don't seem to value high-quality UX work any more. At least not as much, and as generally, as was expected in the dot-com years. More typically, nowadays, they seem more interested in visual appeal, and being 'on trend'.
-- I've also heard that UX is not really important because new users are 'digital natives'.
-- I can make a LOT more money, and find more jobs, slinging web front-end code (Vue/React/JS/TS/etc.), than I can doing UX work.
