Wooden furniture used to mean one of two things: something heavy and brown that belonged to someone's parents, or flat pack veneer that swelled the second a glass of water got near it. That middle ground, solid wood that's actually built well but doesn't look like it came out of a 1987 dining set, has gotten so much easier to find. Better for all of us, especially anyone trying to furnish a real room on a real budget without it looking like a compromise.
Wood is the rare material that gets better looking as it takes a beating, which is exactly the opposite of how most furniture behaves. A coffee table will pick up watermarks, a few dings, maybe a scratch from a moved lamp, and instead of looking tired it starts looking lived in, especially with oak or walnut where the grain only gets more visible with age. A dining table takes it harder, obviously, four meals a day plus homework plus whatever a toddler decides to do with a fork, so wipe spills before they sit, use a mat under anything hot, and give it an oil or wax pass every six months or so if it's an open grain finish. That's genuinely all the maintenance most of these need. What you want to check before it leaves the shop or the moment it's delivered is the joinery, not the surface. Push on a leg, see if it wobbles, check that drawers run smooth and the underside isn't stamped with something suspicious like particleboard pretending to be a frame. A table with good bones will outlast two or three sofas.
If you've got nothing yet, start with a round or oval table in a mid tone wood, something like oak rather than a very dark walnut or a pale whitewash, because mid tones sit happily next to almost any other wood you bring in later and don't demand the room match them. That's the real trap with wooden furniture, not clashing colors but clashing tones, a warm honey oak table next to a gray washed coffee table can look like two different arguments happening in one room. Keep your wood tones within shouting distance of each other and you'll never have that problem. Avoid putting a heavily grained, rustic piece in a room that's otherwise sleek and glossy, it reads like it wandered in from another apartment.
If I had to pick one finish to start with, I'd go with a warm, medium oak. It photographs well in low winter light and still looks right under a bright July window, and it gives you years before you have to think about it again.
