I think a good example for thoughtfully designed user experience for a digital user interface is Medium. Its ultimate goal is to let the user write a post, and Medium has successfully achieved this goal by creating a clean UI that only focuses on blog posts/articles that people have written, also using easy to read font type which eventually makes the user be more confident in what they are writing. The browsing and searching for the article is just a secondary feature. Sharing to social media is also very easy with just a click of a button.

Another good example for good user experience on the digital platform is Amazon. Sure, UI wise Amazon might look cluttered. However, if you are trying to find the product that you are looking for, from the homepage itself there are a lot of interactions that are very intuitive. For example, once we hover onto a category, the menu expands to show us the sub-categories, lead us deeper into the catalogue so that we can find the thing we need within a few clicks. This makes shopping very easy and very fast, thus encouraging people to return to Amazon everytime they need something.
