I thought of Turquoise Bay also after reading the list. It's a little east though - maybe a 10min. drive to the West End for dinner other than the on-site option. Too noisy won't be the problem there.
Or Luna Beach Resort which has everything except you walk/water taxi to the West End for dinner or water taxi to Wet Bay for dinner. It's also really quiet, the road into the resort only goes there. It's on the east end of the West End a little removed from everything else. About a 10min. walk along the beach to the West End. There might even be a shore dive there once you snorkel over the grass - it's just a pretty long way out.
About the only shore dive on the north side off a dive resort is Anthony's Key and it's shallow and not great. Neither is their beach. Plus it's an AI only so you're paying for food you may not eat. About 5mins. by cab to the West End. There was a BOGO going on, IDK if it still is.
I wouldn't necessarily rule out the nicer properties in West Bay either since some have all of what you want. And the cruise excursions pull out mid/late afternoon since they have to return to the ports on the southside for the sailing - Roatan is only a day port. If your third dive is 1PM or later - a few operators do 2PM, you'll miss most of that by the time you return. Check the port schedules, maybe you can pick a week to minimize that as well.

- same spot near Infinity Bay - btw...guess which is the PR photo for the resort. LOL.
I can't really think of anything in the West End that meets your needs. Mid-week and later it's pretty noisy heading up to Friday night. We stay on the east point of Half Moon Bay and we could hear it drifting over slightly over the noise of the ocean hitting the ironshore. It's fun but if it's not your thing...Most of the resorts in that area are across the main road from the beach - some fronted by bars/restaurants. It's really not a great beach either except in one area - Sundowners Beach Bar is on it. A couple of the properties have designated areas with chairs etc. Sueno Del Mar is an average hotel that's on a small strip of beach slightly to the east of "downtown" West End. They have their own dive operation.
Here's a pretty complete list of restaurants:
The 10 Best Roatan Restaurants - TripAdvisor
Notice is most are in the West End/West Bay. The 1/2 dozen in Sandy Bay would be close to Turquoise Bay.
Can't go wrong at Argentinean Grille or Tong's Thai. Rotisserie Chicken for a more casual meal with great food. Consider the source also -
Ooloonthoo is arguably the best on Roatan - maybe the best in Honduras - yet it's ranked 20th? Rotisserie Chicken is #2 for the food only, it's counter service and almost fast food except for the few tables out front - anyone calling it 10 best has been eating at McDonalds too long.
Note - I linked the wrong sort so click ranking at the top.
