Yesyesyesyes! I do wish I could think of more examples supporting both well.
VSCode is probably the best I can think of, where keyboard shortcuts can get you up to a decent speed as an advanced user, but mouse clicks provide an easy intro for a new user.
For the most part, I see tools like NVim, which is super fast but not new-user friendly. Or IOS, which a toddler can navigate, but doesn't afford many ways to speed up interactions like typing.
