I reuse SLIME's inspector for other Lisps. This is Elisp, for Elisp:

    (defun inspect-in-slime ()
      (interactive)
      (slime-inspect
       (format "%S" `',(eval
                        (elisp--preceding-sexp)))))
    
    (add-hook 'lisp-interaction-mode-hook
              (lambda ()
                (local-set-key (kbd "C-c I") #'inspect-in-slime))) 

You only cover a subset of your Lisp with this (without additional work), but it's a useful* subset and you get it essentially for free, for anything that "looks close enough" like a Lisp. And you get SLIME's polished, feature-rich inspection TUI, also for free.

*(Particularly in Elisp, since Emacs uses lots of large cons-cell data structures that are very unpleasant to read!)
