I believe everything you want to do then can be put together with jekyll, scss, and js. Jekyll, in this case, would replace Parcel. At least for me it looks like they kind of serve the same purpose. Jekyll handles scss well and the correct links, so it is fine, and also with a simple bundle exec jekyll build or bundle exec jekyll serve you can get your final site up and running.
Check, for instance, Jekyll Showcase! - Share your sites built with Jekyll and Jekyll Theme Showcase! - Share your Jekyll themes.
