In that class of boat, the owner is not the one operating it. Many times they literally wouldn’t even know how to start the engines much less interact with the ships systems.
Even in that class of boat the owner will typically have a coxswain on his beck and call whenever he fancies going on a jolly.
Some people have chauffeurs, others have a boat and coxswain ... sometimes the coxswain doubles up as chauffeur if the owner isn't quite rich enough to employ more than one person.
Then you'll see MFDs from Garmin, Raymarine, etc.
I had Raymarine Axiom's on my last boat and they were pretty modern. You could display charts, radar, sonor, engine data, all mixed and matched on various layouts. I could even watch Netflix at the helm if I wanted.
Personally, looking at the modern B&G devices[1], I find their UI pretty slick. Also super nice to get all needed information by just glancing at the display
