The young people I know have a very different idea about what "entertaining" is than we do. They need the space because their version (and ours, when we were young) involves a whole bunch of their friends, lots of drinks and snacks and music, and general horsing around. We are more sedate about the whole business. But I disagree that just because you do things only once a month, you shouldn't have a house that supports them. I have four people at my table as often as once a week, six once a month, and eight or ten three or four times a year. Then there's the occasional cocktail party for 20 or so, which is about all this house can handle. I want all those groups to be comfortable, and to feel that we made an effort on their behalf. I want to be able to handle them all relatively easily, which keeps it fun for me. But back to the molding - I don't think it's necessarily about showing off. It's about an old-fashioned level of formality, and a signal that life is lived a certain way in the house. And it's also a pleasure to look at. I don't think anyone should feel uncomfortable in beautiful surroundings, even if they aren't part of one's everyday life. The best advice I ever heard given to a young person about to be entertained in a place that scared her to death was this: "Don't worry about not fitting in. Just stand up straight, smile at everyone, and speak clearly, softly, and rarely."

JJ, just found this thread, sorry no one responded. There is a huge coretec discussion which has over 3000 responses, in that discussion multiple people have not been happy with the quality of the transitions. Some have bought their flooring from an online distributor who color matches better quality transitions (think it was Nice Floors), others have their installer play around with stains and make their own transitions. Sorry this response was so late, hope you haven't been waiting to make a decision.

Thanks for the input - I see what you’re saying. If not crown molding, what other options are there to finish the seam between the tiles and the ceiling that you think would fit? I really feel like it looks unfinished with just grouting..

That sure looks like a "bullnose" (finished edge) wall tile being used at the floor. If so, those will fail. If it's all wall tile used, the entire floor will fail (thinner tile). It looks like you have LVP butted up against the "bullnose," where they will expand and contract. You can already see a couple cuts riding up a little higher on the curved edge than the others. A proper install would be no "bullnose," providing a gap at the end of the vinyl planks, and a Tee transition.
