There is an ECS port for Godot named Godex, but it isn't hugely mature:

https://github.com/GodotECS/godex

I haven't used it, though I've been curious about it. As far as better options for ECS game engines go, I'd go with Bevy (personally), but you'll have to learn Rust (which I'm a proponent of anyway).

But both of these are still in "Beta", if that's even the proper term for their development cycle, at this point. They work, technically, but they could use some help, to my understanding.
