After browsing my CCNA Security books I noticed that it recommends blocking a large range of ports used for different services on the router and that are insecure on end devices. After compiling them all together, here is a working ACL that can be implemented.

Keep in mind to change the RFC1918 (implemented to conform with RFC2827) blocking depending on the topology and that this may block services that you want running.
