The one thing worth knowing before you buy any kitchen cabinet is that the box matters more than the door. Doors get swapped, painted, replaced in ten years when you're bored of them. The carcass, the actual box behind that pretty front, is what you're living with when the hinges start to sag and the shelf starts to bow under a stack of plates. Put your hand inside, press on the base and the sides. If it flexes or sounds hollow and thin, that's what you're buying, no matter how nice the door looks.
Where these go wrong is when people treat them like furniture instead of fittings. A freestanding storage cabinet dropped into a kitchen that's short on built in storage is a fine fix, but it's not going to behave like a proper run of fitted cabinetry, and it won't hide plumbing or give you the same continuous counter line. If you're after that seamless wall of storage, a single stand alone piece is a patch, not a solution, and it's worth knowing that going in rather than being disappointed later. They're also a poor choice for anyone chasing a totally uniform, built in look, because even a close color match will read as a separate piece once it's sitting next to fitted units. Measure the width and depth of the space twice, once with the tape and once by actually standing a chair or a stack of boxes the same size in the gap for a day, because a number on paper and a box in a doorway are not the same experience. Leave room for the doors to swing fully open without clipping a handle on the fridge, and check the height against your counter, not just the wall, since a mismatch of even an inch looks wrong every single day.
As for wear, solid wood cabinets will take on knocks and a bit of color change near the sink and the stove, which is honestly how they're supposed to age, and a light wax or oil once or twice a year keeps that looking intentional rather than tired. Painted MDF doors hold up fine to wiping down but chip at the corners eventually, especially near handles, so touch up paint is worth keeping on hand from day one. Hinges are the first thing to loosen, so give them a turn with a screwdriver every few months rather than waiting for a door to droop.
Would I still want this cabinet in five years, once the doors have taken a few knocks and the kitchen around it has changed?
