Which food is safe during pregnancy

Is it safe to eat/drink:

Cooked sushi such as shrimp tempura, or imitation crab? What are the safe to eat sushi types? I want sushi so bad 😭

Eggplants? Heard lots of it might cause miscarriage(not sure how accurate that is)

Drink decaf coffee?

Drink caffeine free Pepsi?

I never liked sodas but ever since i got pregnant i have been just craving pepsi every single day!
