Very nice! You hit close to home here! Several ideas that are definitely worth looking into. My problems, which might not be profitable to fix, are:

Very few pieces are composable, we need more things like https://www.prettypegs.com/ Unless you have the capability to build a new IKEA, this is to me the best venue for providing high quality customizability.

Finding furniture is a mess. There's missing information (dimensions, max load), close to useless search, and a bunch of places that sell the same things.
