What makes a rifle a *"beginner"* gun?

I am shopping for my first AR, or rifle in general. I do own a beretta pistol for protecting myself and family in a dangerous area, but in my research I see "good for "beginners" a lot. I don't understand how this term applies to a firearm. I own a beretta, it is carried by professionals- police, the army, etc. but it cost no more than the average pistol. What makes say an m&p sport II/III or a palmetto state "beginner"

Are they less modifiable? Cheaper manufacturing/materials? This is an honest question and not a rant, I am just trying to genuinely understand the concept of beginner rifle, when most are milspec, etc. I want to make sure my purchase is sound, safe and durable.

Thanks in advance for entertaining the dumb question!
