Hopping back into COD

Hello! I just bought a PS5. I haven't played COD since World at War. I'm kind of itching to dive back in, but I heard that COD is in a rough state at the moment.

What COD would you recommend jumping back in to? Is the multiplayer on the any of the new ones worth playing?

I'm 30 and work full time, so I'm not trying to be super competitive either.
