Freestanding cabinets get a bad rap for being the thing you buy when you can't be bothered to work out built ins, and honestly, that reputation is half deserved and half lazy. A good one isn't a compromise. It's furniture that can move with you, which matters a lot more than people admit until they're the ones leaving a rental and realizing the cabinet they love is screwed into a wall that isn't theirs.
These work almost anywhere you've got an awkward run of wall and no appetite for a contractor, which is most rooms in most houses I've ever lived in. A hallway that needs somewhere for shoes and mail. A dining room with nowhere to put the good plates. A bedroom corner that's been empty since you moved in three years ago. In winter, with the light low and amber by four in the afternoon, a cabinet with some depth to it and a warm wood tone makes a room feel more settled than it has any right to. In summer, lighter finishes keep the same spot from feeling heavy when the windows are open and everything else in the room is trying to breathe. Wood ages the best of any material here, picking up a little color and a few honest marks over the years, which is part of the deal rather than a flaw, so don't panic the first time it gets a water ring. Wipe spills fast, keep it out of direct sun if you can, and give it a wax or oil every so often if it's an open grain finish, that's really the whole maintenance plan. Painted and veneered versions need less fuss but show chips more, so a coaster habit matters more there than people expect. In an ordinary room, a freestanding cabinet sits well against plain walls more than busy ones, pairs naturally with a rug that has some age or texture to it, and does better next to soft lighting, a lamp on top or beside it, than under a harsh overhead. It doesn't need matching furniture around it. It needs a bit of breathing room on either side so it reads as a piece rather than a slab.
When you're looking at one in person or checking it the day it arrives, run your hand along the back edges and the inside of the doors, that's where cheap finishing shows up first. Open every door and drawer, more than once, cabinets that feel fine standing still can rock or stick once they're loaded. Check the feet are adjustable if your floor isn't perfectly flat, because almost no floor is, and look at how the back panel is attached, a flimsy stapled back on a tall cabinet is asking to bow under weight. Keep it out of direct sun and off a damp floor, and it'll outlast most of the other furniture in the room.
