#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

The recommended fit around a DR table is 24" larger on all sides for the chairs. You won't have that on the 6'8" side. I'm thinking the rug is going to be too small for the room 8x10 or even 9x12 would have been a better choice.

have your dining near the kitchen as it's better for accessibility. TV should not be opposite any window to avoid glare. keep the tv in the center and living room around it. Do not divide the space with a divider since these days the trend is to have open floor plan. If you divide then the space will look small.

Better to opt for L-shape sofa for the above position.. Bedroom appears to have occupied more space than living room. If it's already finished,. you may have to opt for compact furniture,.. Or reduce the size of bedroom first; then proper living/dining arrangements can be done.
