I have tried the Remi wizard.

I have also checked selinux:

> setenforce 0
> sestatus | grep "Current mode"
Current mode:                   permissive
> php -a

Re: PHP Startup: Unable to load dynamic library issue

You have

> /opt/oracle/instantclient_19_18/

You need

> libclntsh.so.21.1: cannot open shared object file: No such file or directory

So you need to upgrade to client library version 21
