Topic: mapping components and wit to various languages

Is there some kind of summary page showing how WIT and WASM components are "canonically" mapped to various languages?

For example, what does a "world" look like when I'm in Java, in Rust, etc?

There is not, afaik

The closest thing available now might be https://component-model.bytecodealliance.org/language-support.html

Note that the state of Java support for WIT is in limbo right now. See https://github.com/bytecodealliance/wit-bindgen/issues/1010 and #wasmtime > Java Component Model Support for details.

TeaVM bindings for resource types are un-implemented · Issue #1010 · bytecodealliance/wit-bindgen
the lib.rs in teavm-java seems to have a number of todo! macros currently, which prevent bindings being generated for any .wit files containing resource types.

AFAIK going forward documentation on language semantics/mappings should land in the component-model book and relevant toolchain repositories (be they examples or guides), with links going between the two as necessary.

While the component-docs repo is likely to be light on code for every language under the sun, the language toolchains should have more examples that showcase functionality.
