Thinking about getting Z-A for Switch 2

Hi everyone, I’m thinking about getting Z-A in the next week or so but I have a few questions first for anyone that played the game.

1: Even tho is a small Map featuring only the City does it have diverse environments? Maybe a Graveyard or hotels to explore or I don’t know a Factory section? I really like exploring in Pokémon games and I liked a lot the vibe of Legends Arceus.

2: Is it a small game ? How long did it take you to complete it?

3: does it have any replayability?
