It does exist. It's your regular C++17 with Google Style on top (though perhaps with exceptions allowed), ruthlessly enforced through reviews. For larger teams to talk to each other use Protocol Buffers and GRPC to decouple interfaces. For build use Bazel. For utility code use Abseil. Do not use Boost for anything. For editing, set up Vim/Nvim + YouCompleteMe.

With this setup I find C++ pretty easy to work in. And I've built a team of ~50 devs that were productive on the same multiplatform C++ codebase (+ all sorts of language bindings).
