>>6957I'm not sure what you are looking for. You haven't mentioned Lojban, that's also a semi famous constructed language. It tries to be syntactically unambiguous.

You can't construct a new language from scratch and expect everybody to just switch to that.
You have to take common organic languages and improve them slowly. Make them easier to learn with more consistent rules. It has to be slow so that improvements can filter down into actual use and pass the test of getting accepted by the masses. A second objective is to blend all these languages into one common one, by introducing words from one language to another. By trial and error you'll find out what words, sounds and other linguistic constructs are universal enough to stick with everybody. And over the course of 200 years you'll end up with an international language, that is constructed and derived. The goal would be for most people on earth to know it as a second or third language.
