Dumb question: do you have access to any of the nice text rendering features of the browser when you use Wasm, or is it basically just drawing to a canvas

There's no difference between WASM and JS in this situation.
Once you are in canvas land, you'll have to do the text rendering yourself - that's not the fault of JS or WASM though, but of the broken web API stack (what's there is not properly layered, and the whole layer stack is inverted, e.g. canvas sits on top of the DOM instead the DOM sitting on top of canvas).
There is an Emscripten library which cross-compiles things to WASM. The means you can generally just pull in a dependency for font rendering, such as SDL_ttf.
