Most open source development is the result of people 'scratching their own itch', not randomly selecting a project to 'help'. So if I, hypothetically, was to contribute it probably would be to an engine I was actually using ;) Godot seems to be furthest in developing a GUI-first engine which is what most people find more approachable since you don't have to learn coding to get a simple game to run. It will profit from network effects due to its growing community. Bevy is a great engine too, but there are literally hundreds of 'library based' game engines. Also, it requires you to learn Rust first which makes it more of a niche.
