Forgot about the SD Card and battery since I don't miss those either, but true, if it's something you're used to, well then steer clear of the last Samsung batch of phones.
Also a good point about the screen protector. Since it's curved, you're pretty much stuck with thin-film ones, and even those are tricky to keep in place. As for the case, it helps that once you register the phone you get a 50% discount in the Samsung store which you can use for a new case on the cheap, and if you on top of that register Samsung Pay with a compatible card, you can get whatever the current promo is, and I believe there's one for 100 bucks in Best Buy cards or a 200-dollar gift package (not sure if the latter is still active as it was for the holidays). Also, if you have a Citibank card, there's an offer to get credit back when you use it for the first time.
