I'm guessing I'm over twice your age but my situation is similar to yours in a couple aspects. What I decided to do is focus on exploring the new capabilities that AI will allow individuals to do (especially those of us who can code). There are a lot of ppl who are justifiably frustrated with the current state of the tools. But don't get discouraged by that. I've seen A LOT of tech waves. It's still early in the AI era. I won't suggest any particular approach but recommend giving it some thought.

BTW, being an old timer, I also hated the leetcode thing when it became a widespread thing after Google adopted the practice in the wake of The Joel (Spolsky) Test. But you know, years later when I had to go through some interviews, I did spend a few months studying it and it turned out to be pretty fun. But passing technical screenings didn't help me land a job... only connecting via my network seemed to make any difference.
