“Any thoughts on 18" front to back vs. 19"?!” @kel_kat5 - the sink’s front-to-back measurement can be important depending on how much room you’ll have behind your sink for the faucet. There have been a number of occurrences of people installing a sink, and then finding there isn’t enough room for the faucet, or for the faucet handle to move fully. This can be more the case in front of a window. Many people with this issue get a faucet in which the handle can be moved to the front, rather than be on one side. An advantage to this is that dripping hands on the handle don’t leave water all over the counter. For my next kitchen, I am doing this with my faucet, even if I have plenty of space. I am always cleaning mineral deposits and soap scum on the counter directly under the faucet handle where wet hands drip. Here is a thread about it: https://www.houzz.com/discussions/2442104/positioning-single-handle-kitchen-faucet

Yeah, the last thing I would do is divide the room into separate kitchen and dining/living room areas. I just got done tearing down such a wall, in a house that's considerably larger (5BR / 2-1/2BA) to make a large kitchen/dining/living room where everything melds together. Many people are either renovating their older homes to achieve that or buying new ones that start out that way, because it suits how many of us live nowadays. Kitchens are no longer private areas where someone labors for hours a day to prepare family meals; rather it's a gathering area with cabinets and appliances designed to look good, and thus it's a room you want your guests to see. Fewer people want formal separate dining rooms anymore - why reserve the nice table, chairs, and china for a few special occasions each year? With your home I'd arrange everything so no matter whether you're preparing food, eating, cleaning up afterward, socializing, or watching TV, you sit or work in a large room with those nice views unhindered. I'd also nix the big range, and consider a good 24" cooktop - several have small knobs in front off to one side such that it leaves almost the entire surface for burners, rather than the traditional 6" of width at the right used for controls, so you still have a roomy surface to work on. (Personally, I'd be fine with a 12" or 15" wide two-burner setup for a 2BR/1BA home, but I know many others wouldn't be). I'd also consider a 24" undercounter oven. I used one with a side-hinged door, glide-out racks, and a very slim control panel at the top so the oven cavity is as high as possible. I don't need to lean downward to insert or remove food from the top rack, and the door and slide-out rack arrangement means I don't ever have to lean over or around an open drop-down door like you would with most ranges. And there's room for a drawer underneath it, great for baking tray storage. If I need additional oven space, I have an Advantium high-speed oven that can also be used as a conventional oven or a microwave. These (and other similar units) are available in wall-cabinet, undercounter, and over-the-cooktop configurations.

I don't have the sink/counter installed yet but I'll post a picture of what I got going on. Also have 2 drain pipes so I'm thinking if the one is to high I could use the other one.

My sinks are custom because they are integrated into the counter but they are NOT much deeper (front to back) than typical large sinks (and any extra deepness is in front of the sink--I got those things so close to the front of the cabinet I had to relocate hinges). You don't want your sink so deep that it's hard to reach the faucet, or the water flow is too far back. Anyway, a regular undermount sink will look just fine--nobody will notice.
