The great thing about TUIs is that a simple text component is a universal widget. If the user can display text and capture events they can implement any interface components they want in terms of that.
That said, whatever the framework provides pushes users in a particular direction. The core of the things I'm thinking of (some links below) is providing easily accessible context for the user right at the point where they are working. This can be completions at the cursor, or a quick key to pop up a command palette. Fuzzy search is standard.
I've included links that have screenshots showing how they work. The list is biased to Emacs, because I'm an Emacs user (Doom Emacs in particular) and so more familiar with that ecosystem.

Here are some examples:

* Vertico: https://github.com/minad/vertico
* which-key: https://github.com/justbur/emacs-which-key
* LazyVim: https://www.lazyvim.org/

Hope that helps!
