The default location now is
/var/www/html/
That should be the location of the "default page" index.html you are seeing.
If you move your content there, assuming you only run one site from the server, it should serve it.

...I didn't mention documentroot which needs to change too.
You might like to try this (comments not reproduced, no opt-related directory stanza required in apache2.conf as long as it's specified here)
---
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /opt/what/ever/
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
<Directory /opt/what/ever/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
---
There can only be one
<VirtualHost *:80>
in all of the sites-enabled/*.conf files, which is served if no other virtualhost matches the incoming domain request (by the ServerName or ServerAlias).
So if you want to create another sitename.conf to serve from /opt and leave 000-default as it is, you will need to change your file to something like
<VirtualHost your-ip:80>
ServerName www.yourdomain.com
...
(rest as above)

Not that I know of.
000-default.conf gives the basic structure but not all the options.
