Kind of tricky to answer because I feel like neither the description given for "style" nor the description given for "function" fit. I'm somewhere in between.
I do use the "move objects" cheat frequently to make things look more natural and not so artificially spaced out. But since I mostly only build for my own use, it's very quickly apparent to me if something is having a routing issue and I fix it. I like having a lot of detail, and the style/story/atmosphere of a room or lot is super important to me, but it all has to be functional too. I try to avoid having things blocking my view since I take a lot of screen shots (but I'm also really good at maneuvering the camera into angles that might seem hard to get into), and I absolutely can't stand any glitching or flickering in play mode.
I do occasionally participate in build challenges, and in those cases I try not to use "move objects" at all except for the decorative plants outdoors. I play test every interactive object on the lot to make sure everything is rout-able before uploading because I know that anyone who downloads the lot will not want to spend time fixing my routing issues. I also go very sparing on the non-interactive decor, especially on surfaces like shelves or counters, so that players will have room to place their own treasures. However, these occasional build challenge entries are the only time I put my builds on the gallery. For my own use I take more risks and clutter more because, well, it's my problem if it doesn't work.
The only times I have used "move objects" in a really unusual or creative way, such as combining objects to make something else, has been for SimLit screenshots when I couldn't find cc that resembled what I wanted. In those cases, it's not intended to be something sims will interact with, its just something I need in the background for the shot.
