Thanks for developing this wonderful tool. Just tried it. The HTML output looks great.

I use R Markdown extensively. I am wondering if R Markdown is retiring? Should I begin to switch to Quarto? And is there a way to change the default code font to ligatures fonts (for example Fira Code)?

Quarto is the next generation of R Markdown, so over time it will surpass R Markdown in features/capability (I think in most areas it already has). Note that Quarto will read and render existing Rmd files without modification, so when you decide to switch isn't a terribly big deal. You can use the monofont option to specify an alternate code font.
