Disclosure: I'm not a theoretician, but just an old industrial physicist who helps design measurement equipment. What I've noticed is that most physicists are aware of the great epistemological puzzles, and may even have briefly dabbled in them, but also tend to ignore them if there's work to be done. There's a lot of pleasure and utility to be gained from just finding a hard problem and working on it, maybe even solving it, or inventing something. When people find out that I'm a physicist, and ask me about those puzzles, I usually plead ignorance. I'm not dismissive of them, or anti-intellectual, but I think you shouldn't let them be an obstacle to the enjoyment of physics, either as a spectator or practitioner.
