The only thing that truly changes over time is their bodies. They grow bone armor. Their brains, however, stay the same.

Oobleck (The most useful source of information in the main show for Grimm) himself states that Grimm grow more powerful as they grow older, and that not all Grimm are still mindless. You also, in my opinion, made a mistake: intelligence is exactly what you stated, you gain intelligence from learning from experiences, like you said like most animals-including us. It was never about brain size, although as a Grimm's body grows, surely their brain will also grow? Learning is gaining knowledge, and this knowledge allows these Grimm to do different things.

What I hypothosise is (and this stands to your reasoning as well), if a Grimm spent enough time associating actions to words that Humans speak in the field, would they begin to understand them? We've heard nothing of Grimm dying by old age, so perhaps they cannot die from old age. And I'll give you this, animals that can learn from their pervious actions are considered amongst the smarter ones, with the most advanced brain structures, if the Grimm can learn, then they are an intelligent animal and can grow in intelligence.

I really like this sortof theorycrafting, even if it's a bit 'out-there'.
