What are some classic DND enemies to fight in a beginner campaign to give someone a taste of DND?

I'm thinking about a simple campaign in a town where some goblins raid a few homes and steal some important items, and the goal is to get the items back

Along the way to the goblin camp, they find some enemies to fight, spiders or wolves

And then break into the goblin camp through a basement with some rats, eventually leading to some goblin combat, where the goblin boss has a caged owlbear that is released as a "final" boss

I might include a mimic after this fight as a special surprise as well

What are some other classic DND enemies I could pepper throughout to give my players a good taste of what DND is?
