I certainly spent most (95%+?) of my "fighting the borrow checker" time writing code I would never try to write in C++. A simple example is strings: I'd spend a lot of time trying to get a &str to work instead of a String::clone, where in equivalent C++ code I'd never use std::string_view over std::string - not because it would be a memory error to do so in my code as it stood, but because it'd be nearly impossible to keep it memory safe with code reviews and C++'s limited static analysis tooling. This was made all the worse by the fact that I frequently, eventually, succeeded in "winning". I would write unnecessary and unprofiled "micro-optimizations" that I was confident were safe and would remain safe in Rust, that I'd never dare try to maintain in C++. Eventually I mellowed out and started .clone()ing when I would deep copy in C++. Thus ended my fight with the borrow checker.
