Do you want 4k, or is "non 4k" sufficient?

If you DON'T need 4k, you might consider a 32" 1440p display.
 
Is the one I linked to in my first post any good?
Ideally want 4k but that's just a want. I use it for lots of cloud apps, spreadsheets and email so just need lots of screen real estate for open windows.
 
I have a Dell 38" curved (U3818DW) that works well for me. I'm not in photography or video editing. I mainly live in command prompts and office documents and I like being able to spread multiple windows across the monitor. Monitors are such a personal decision so not sure what works for you, but I've had no problems with the monitor working with my MBP.
 
Need a large monitor 27" or above, can be curved or normal.
Needs to work well with MacBook Pro 15" 2018 model.

Recommendations please.

I'm a fan of the LG displays. Like that the one you've linked also looks to match well with Apple hardware.

I use 34" curved displays both on my gaming PC and another one for my work laptop. They're the perfect size for having applications open side-by-side without needing to scroll horizontally.
