biblatex-apa succeeds in suppressing punctuation after the URL if it comes at the end of the entry, but if the bibliography driver prints something after the URL that does not always work.

Not quite sure how one would resolve this properly. Controlling the punctuation after the field is always tricky I'm thinking \nopunct might help to some degree...

\DeclareFieldFormat{url}{\url{#1}\nopunct}

or \printunit...

\renewbibmacro*{doi+url}{%
  \ifboolexpr{          test {\iffieldundef{doi}}
                 or not togl {bbx:doi}}
    {\ifboolexpr{       test {\iffieldundef{url}}
                 or not togl {bbx:url}}
       {\newunit}
       {\usebibmacro{url+urldate}%
        \printunit{\addspace}}}
    {\printfield{doi}%
     \renewcommand*{\finentrypunct}{\relax}%
     \printunit{\addspace}}}
