There are a handful of apps that aren't supported, but few of these are popular apps. Virtualbox is notable, but unsurprising: Rosetta is not designed for x86_64 virtual machines, and Virtualbox doesn't support arm64. (I submitted a correction to the Wine entry, since wine64 has worked under Rosetta 2 for a year.)
