> Given React and Next’s wider use and longer history, it’s likely most LLMs are trained on more React and Next code than Svelte code. Ditto for FastHTML. This could lead to coding assistants being more effective when working with and suggesting code for established frameworks such as FastAPI, React, and Next.js.

Yes, but also more stale code from old versions which use patterns that the community has for various reasons moved on from. I ran into a lot of trouble with deprecated patterns while teaching myself react last year with assistants on the side. React 17 and prior version patterns kept coming up all the time.
