Perhaps the name `sort-by' would be more consistent with the
`seq-sort-by' function defined in lisp/emacs-lisp/seq.el?

                                ^^

Out of curiosity, is there a preference/convention
for/against `function'-quoting lambdas in the Emacs source
tree?  The only reason I avoid it is because it breaks the
fontification of `lambda' as a macro. :)

>   (setq seq (sort* seq #'(lambda (x y) (funcall predicate (car x) (car y)))))
               ^^^^^

Is this not the same as using plain `sort' here?
