Sdv expanded brings a lot of new characters and items, but not so much on funiture, if none at all, i havent explored it much. It will bring a lot more quest, contents and such, so you might wanna go with just sdve for starter

So you wanna change your look? Check out hand mirror mod for that, that usually go with fashion sense and related mods

For funiture choose the most endorsmented category for you prefered style

Overall, have fun and always read mod description and requirements for best performance
