I'm not ready to try to stake a position on the top of some "composition first" hill because the syntactic composition it supports is not something I use all the time. It's an occasional convenience more than a fundamental primitive in the language, the way inheritance is in inheritance-based languages. Most of the composition is just done through methods that happen to use in composed-in values, but it is generally not particularly supported by syntax.
Rust has support for variance and subtupint so perhaps it's not as pure of an example, but it's pretty heavily restricted.
Zig's support for method/data bundling being used for "objects" isn't even first class so I wouldn't call it OO (object-oriented) so much as object-orientation-capable with less fuss than if one wanted to build their own objects system in C.
Dynamic dispatch is the defining feature of object-oriented programming. In dynamically typed languages such as Smalltalk, you can get there with duck typing. But a statically typed language needs a statically typed mechanism for dynamic dispatch, and that requires some way of saying, "Y is a particular kind of X, so all members of X are also in Y." Which is - again by definition - inheritance.
You could remove - or refuse to use - the inheritance (or, equivalently for some purposes, duck typing). But that would also prevent the use of dynamic dispatch, so what you're doing would bee be procedural programming, not OOP, even if you're using an object-oriented language to do it.
Message passing is the defining feature of object-oriented programming. Dynamic dispatch can be achieved using message passing, but message passing is more than dynamic dispatch.
Ultimately, static typing is incongruent with object-oriented programming. Messages are able to be invented at runtime, so it is impossible to apply types statically. At best you can have an Objective-C-like situation where you can statically type the non-OO parts of the language, while still allowing the messages to evade the type system.
It's unfortunate that inheritance became such a major focus of practical OO languages. Would love to see a composition-first OO language. Might have its own problems, but would at least be interesting.
