Perks of using Jekyll for your projects:

• No backend/databases (yes, I consider this as a huge benefit, especially if you are just blogging)
• Static files, all you need is html + css and sometimes some simple javascript logic (for slider f.ex.);
• Markdown - it is easy to document and write posts
• Plugins - jekyll has some awesome plugins for SEO, asset management and etc.
• Hosting - it is easy to host, even github pages can host jekyll website

What packages and tools I am using

For my blogs I usually reuse the same plugins, the most useful I found are these:

"jekyll-assets"
"jekyll-seo-tag"
"image_optim"
"image_optim_pack"
"mini_magick"

CI/CD

Since github is capable of serving jekyll websites it is quite easy to setup whole pipeline for testing, building and deploying your jekyll websites. You can use github actions to build and deploy your website. You can find the configuration in the .github/workflows/github-pages.yml file.
