Yes, my interest is basically at a level slightly above the OS, not bare metal embedded or OS development per se. And the OS (at least Linux) will tell you which features a given CPU supports. It's just that the variety on the 32-bit side is so enormous, it's hard to be sure of anything. I.e. your particular chip might not even have hardware FP. With aarch64 even the lowest common denominator is better than just about any arm32 (modulo the specialized extra hardware the particular chip might have).
