This is a great post discussing the differences between the different communist ideologies but don't really talk about yugoslavia or albania (other than a passing reference but doesn't talk about it)

This thread is specifically on how the communist government of yugoslavia functioned amd what it did

This thread doesn't really talk about how the communists in albania functioned bur does talk about the events and causes leading up to the election of the socialist party

Unfortunately, I couldn't find anything talking about how communism in albania differed or functioned

Missed the rest of what you wrote outside the title after I made my post so I might as well make a new reply rather than edit it

The second answer is more relevant to your question as it explains why the government in cambodia became what it was IMO
