Another very useful project is SingleFile. I was ecstatic when I found out about its existence.
https://github.com/gildas-lormeau/SingleFile
"SingleFile helps you to save a complete web page into a single HTML file. SingleFile is a Web Extension (and a CLI tool) compatible with Chrome, Firefox (Desktop and Mobile), Microsoft Edge, Safari, Vivaldi, Brave, Waterfox, Yandex browser, and Opera."
Don't most browsers do this natively? Firefox saves single pages as html. Chrome saves pages as mhtml which isn't supported in firefox but can be easily converted if there's ever a need.
I use LinkDing for website bookmarking and storage/archiving needs. It is a great and stable piece of software. It archives using a Chrome web driver. Sometimes that fails, e.g. on Captchas, very heavy JS sites or sites behind login. Those I save with SingleFile and attach in LinkDing manually. Simple and works!
