I mentioned `set-variable'. But it is only for user options. (And there is already a link to Customize for the variable being described.) And there's `M-: (setq...)`. But for that what's missing is the ability to insert buffer text (e.g. a variable name at point) into the minibuffer. (See the discussion in bug #36525 about that.) And see discussions in emacs-devel: 2017, "custom-set-variables considered harmful", 2011, "set-variable and defcustom", 2010, "`set-variable' should use :set", 2007, "customize-set-(value|variable)", 2007, "apropos commands for commands, user options, all functions, all vari= ables".
