Sounds like you are letting outside influences (either in person or on the interwebs) dictate what you think is good. This seems evident by your use of the term “boomer rock”.

I have a wide range of musical tastes, including plenty of classic rock. I never worry about what others think and listen to what I like.

All of that being said, considering you used to dig metal, maybe try some modern prog/prog-metal to see if any of it hits you. Check out bands like Tesseract, Voices From The Fuselage, Thank You Scientist, Protest The Hero, Porcupine Tree, The Contortionist, etc.
