Amaya Lake Lodge has some smaller side rooms that don't have too much space to light nicely with various lamps, and the sunlight that comes in through the bedroom windows during the day is really nice.
If you can get hold of Varla and Culanda stones (they are in the Luxury Vendor's rotation), putting one of each together and then embedding the two well into the ceiling provides very bright white light that illuminates a large area. I've put that setup in my Hunding's Palatial Hall upstairs with my outfit station and it's REALLY well lit. In fact I'm about to move the lights up a bit higher. I have not experimented with other sets of blue and yellow light but generally if you have a blue version of something, like some of the daedric braziers, and then a yellow version like a regular fire one, and you put them right on top of each other, the combined blue and yellow lights make white light.
Idk of any houses that are extraordinarily well lit but, I live by the Small Psijic Water Globes, the light has a blueish hue to it but the Light Radius is unmatched by any other Light Fixtures I've seen thus far. You can get a Recipe to Craft them from the Arteum Vendor standing near the Wayshrine after completing a series of Psijic Quests. If you have Summerset Chapter, that is.
