C++ has more features than Rust but you can limit yourself pretty severely and use "simple" features to get far more safety and convenience than C without having to wrap your mind around Rust.
True for your new project from scratch when you already sucked up C++ such that you know what&when.
But at this point you know C++ pretty well (including all what you don't want to use, take a look at the CPP Core Guidelines), and using Rust is almost trivial, since Rust doesn't really introduce anything really new you wouldn't be already familiar with.

At least that was my experience.
