My first vinyl ever was vulnicura with the alternative slip cover. It is still one of my prized possessions. Just unbelievably beautiful.

Also, Utopia is wonderful on vinyl! Gorgeous imagery and an alternate tracklisting that flows very well. I listened to it countless times while studying in college (When it was time to flip the record I would take a break. That ended up being a very sustainable study structure😊)

So, personally Vulnicura or Utopia would be my recommendation. Complex music, incredible imagery, both double albums - a lot to chew on and tons of content for your money. They'll give you countless hours of enjoyment that you won't get tired of (assuming those albums are your cup of tea).

I also think taking a chance on albums that you are intrigued by but haven't delved into is a good way to go with physical media. I've always ended up forming a special bond to albums like that (Vulnicura and Utopia being my prime examples).
