Nothing that prevents me from running an instance of PrestaShop.
In my test/development server's php.ini I've got "error_reporting = E_ALL" and here and there I do get PHP Warnings to server's error log file that are AFAIK related to PHP being 7.3 and not 7.2. But they are just warnings, not errors.
But I don't use every possible feature of PrestaShop and I've got just a small number of third party addons installed. Everyone's milage may vary. Make a duplicate of your PS installation and try to run it on a separate test server using PHP 7.3 before swithing your production server to PHP 7.3.
PrestaShop 1.7.6.3, 1.7.6.5
Apache 2.4.46
PHP Version 7.3.24
MySQL 8.0.22 - but you must set your DB-user's password hashing to "MySQL Native authentication". PrestaShop can't handle the SHA2 authentication hashing that comes with MySQL 8
