Apache 2.4 + mod_php/PHP-FPM + suexec + userdir on Debian 10

I cannot find a working, modern configuration to resolve this. I'm using Debian 10 and installed Apache 2. I have dozens of users, so I enabled userdir. I do not want their code to run as www-data, so I enabled suexec, which works for Python or Perl (AddHandler cgi-script .pl .py is enough), but I cannot do this for PHP. Is there a way to handle this with standard mod_php from Apache, suexec-like with userdir? If not, I read that PHP FPM is a CGI server, which can be used by Apache by proxy module, which can proxy PHP to this CGI, but in the php-fpm.conf I only can set a single user for this. Is there a way to run PHP web script as a user that owns the script, like suexec is doing, together with userdir?
