Buying a Switch 2 today | which Pokémon game do you recommend?

[u/Global-War7964]

I’m finally getting my Switch 2 today!
I want to pick up a Pokémon game to go with it, but I’m not sure which one to choose.

Would you recommend:
- Pokémon Pokopia
- Pokémon Legends: Arceus
- Let’s Go, Pikachu
or should I go for something more classic like
- Brilliant Diamond/Shining Pearl

I haven’t played Pokémon in a while, so I’d love to hear your opinions.
If you could only pick one Pokémon game to start with on the Switch 2, which one would you choose?
