Probably speak to Cloudways support.

Did you (I hope you did) take a full backup of the database before doing the database upgrade? I've never successfully upgraded MySQL/MariaDB with the data in place. I'm sure it's possible but I've always dumped the data, installed the new version of the software and then re-uploaded the databases. However, Cloudways support should know better what is possible.

I'm reasonably sure that the statistics report doesn't have that facility.

First check that $CFG->wwwroot in your config.php file is definitely correct.

I've never heard of eduGAIN but I would suggest looking at the Catalyst SAML2 plugin to see if that achieves what you need.

I'm no expert but SAML2 seems to be commonly supported by Shibboleth.

With one of these hosting arrangements, it's probably simple to create a website and simple to create a Moodle site. But to have both in a meaningful way is dependent on how the hosting is organised and how they intended this hosting to be used.

My guess is that it's a one or the other kind of thing.

As I'm sure you're realising, beyond a certain point you need to acquire some basic server admin skills to be in a position to work around these things (*not* a developer as is often said). None of this is rocket science and should be readily achievable if you have the time and patience.
