When I was using C++ for embedded, which is admittedly over 15 years ago, I had to switch off RTTI and exception handling to get compact binaries. Basically just using classes and surface language features. We did use templates but only very selectively.

Is it still possible today to pare down the compiler output like that? I imagine a lot of modern C++ just doesn't work unless everything is enabled.

Yes it is possible.

Check this talk about fitting C++17 on a C64.

CppCon 2016: Jason Turner “Rich Code for Tiny Computers: A Simple Commodore 64 Game in C++17”

Also be aware that embedded devices like Arduino and Cortex-M (with Mbed OS) do use C++ toolchains.
