Pascal will cover a few of your points and move you sideways on others. For example you do have a required forward declaration but it's all in a single module file. FPC is a good compiler and should cover most concerns around tooling. And it's all been documented in depth at some point, although you might be studying from pretty old sources. But because it remains a pretty simple language, it's not going to have so many nifty time saver features. If you're going for that you might be better served with a "new and hyped" language like D or Nim - those languages aren't as convoluted as C++ but they are still complex.
