I find a lot of Shimrods and Twoftmama mods get rid of a lot of irritating things. For example, better sleep in lower comfort beds lets you use more beds to design your bedrooms just the way you want without worrying they have a bad night's sleep. Getting rid of roaches that you can't see underground at resorts, auto-emptying the potty chair, better routing, resetting the dive caves, less ice cream trucks, no fleas, murphy bed won't kill, zombies won't eat plants, and No Mermaids, No Emigration, No Move, and No Immigration, etc. Mods that get rid of irritants make game play a lot more fun!
Oh, and I forgot velocitygrass over at MTS has some great ones - unlocked simport rewards, remove stencils and deco, and add any lot size.
And, KissingToast has a mod with a lot of store content fixes.
Then there are a lot of shiftable mods that allow more items to shift up and down a wall, like curtains - Alverdine_curtainsALL and granthesAdjustableCurtainsDefBG - or wall lights and paintings - Gelydh - Default - Easel Paintings
MTS is my goto mod spot, but there are other great, trustworthy modders, esp. those from the old simlogical site. MTS has a WCIF section that might be helpful for you too.
