I agree with this (except for the bit about C++ but that's neither here nor there) but what I landed on was that maybe a native look isn't as important as I thought. Some of the nicest apps I've used just have their own look. They're still native and very quick, but they use their own UI toolkit that doesn't fit the system. For example nheko, ripcord, blender, sublime merge, etc.
