I would like to have a large underground room without it being either very dark or have light sources in the open (lava columns, torches). I use to build columns using stairs since they allowed light to pass through them, but this bug no longer seems to work.

Put Steve in a 1x1 hole and measure the wiggle room. ALL the room - WiggleRoom = Steve
In a 1x1 hole, I pointed the camera straight down and moved from corner to corner. Regardless of corner or orientation, the crosshairs pointed at the farthest point of a 5x5 square from the corner.
16 = 5 + 6 + 5
That's 16 total square width, 5 for the each side of Steve, and 6 for the wiggle room.
Front/back/left/right, the closest you can get to a wall is 5. This test is unable to confirm if Steve is 10x10 square, or a 5 radius circle.
Note: this finding contradicts the original question, as Steve is 0.625 wide, and the asker was expecting more than that. However the original question also supports this answer in the door screenshot (5 texture pixels from door).
It seems reasonable to think that Steve is an unrotating 0.625x0.625 square, which is 0.88 from corner to corner, and could not fit through the ~0.7 gap.
Here is Steve (in green), blocked by two stairs (in purple). Steve is 10 units big, but the yellow line is ~14.14 units big, which is too large to go through the ~11.3 unit opening.
I have the following underground farm. It's not optimal in terms of space, but for a farm, it's very efficient, and has automatic harvesting. Planting is always manual on these things unfortunately, and that's the bottleneck for massive production.

I replicate the above pattern, one level up to the right for as long as you want. S is stone. D is tilled dirt. The trick is with the X blocks. They are water blocks at the level of the dirt blocks covered with Stone.

When you view this from the left, you see there's a channel for water to flow out of your monitor. That is what permits automatic harvesting. The water blocks are necessary for hydrating the soil.
On the far right, I place a water gate.

Light will shine through paintings, but paintings have to be placed over solid blocks (which signs count as!), so you could make a wall like so:
The hole in the middle would actually be 2 deep; you'd place a torch in the back, then a sign in front, then put a painting over the hole/sign; the torch would shine through the sign and painting, and light up the room (although the light would be somewhat diminished because the torch is recessed by 2 blocks).
