I work for corporation that is pretty pragmatic about these things. We like to use the newest toys that modern c++ gives us, but since we need to support older versions of macOS, we are limited by what we can use for the lowest supported deployment target.
Given that: Until very recently we used c++17, but with a set of standard library features that was off-limits. Examples of these are things like std::variant (because std::bad_variant_access requires 10.14), std::filesystem (requires 10.15 for std::filesystem_error). We've recently started using c++20, which works fine for all the language features - even if not all the library features are supported. In short: What I tihnk is relevant is is which library features you depend on. Compilers are easily updated, without much risk, but if you depend on library features with a compiled component, you'd need to be aware of which OS-version supports it. macOS is usually the lowest common denominator in this.
