I’m a bit reluctant to change SMT for the good reasons you mention. Resizeable bar is unfortunately not available on my chipset (B350), starts from B450. PBO good idea, I hesitate as it tends to stress processors both in voltage and heat, but I may give it a try. Ran several benchmarks on my CPU (CPU-Z, OCCT), results aligned with Ryzen 7 3700x mean perfs.
