For a kitchen, recessed spots still beat a single flush panel: you can put more light on the worktop and less glare where people sit. Aim for 3000K (4000K can look quite clinical over food), CRI 90+, and a proper baffle so you are not staring into the LED. If you dim, pair a trailing-edge LED dimmer with the driver. Old rotary dimmers are what make cheap GU10s flicker. Spacing is roughly 0.5 to 0.7 times ceiling height between spots, with a row over the run of units rather than a grid in the middle of the room.
