How to switch to a buffer from terminal with a unique partial name

Question

I have a buffer with the name very-long-name-xyz-etc. This buffer is the only buffer whose name contains xyz. From terminal I can switch to that buffer using the following

emacsclientw -cna runemacs --eval "(switch-to-buffer \"very-long-name-xyz-etc\")"

Is there a way to do better by just using the partial name xyz?

Here's one implementation of the function @NickD specified:

(require 'dash) ; for `-find', `-compose' and `-partial'

(defun switch-to-buffer-matching (regular-expression)
  "Switch to the first buffer that matches REGULAR-EXPRESSION."
  (switch-to-buffer
    (-find
     (-compose
      (-partial #'string-match-p regular-expression)
      #'buffer-name)
     (buffer-list))))
