Would you consider building a closet that would hold the platform on which your mattress would be placed? The outer side of the platform could have drawers or doors to the storage units under the platform. This kind of enclosure would work better for a twin bed than for a double, but it would provide a place where the bed can be concealed during the day time. Then, if you could allow a path between the bed enclosure and sofa, you could have the sofa face the dining table, or you could place the dining table at a right angle to the end of the sofa.

One option, I would get a very large rug so that all the chair legs and at least one corner of the sofa is on the rug. I think I would also bring the table set away from the window a little more. I think there is enough space to place the two-seater opposite the table in front of the window. or bring the table forward toward the kitchen ....... With the sofa centered to the large window. They probably will not be opposite each other, but at an angle which is still ok. They might seem more functional for the table set to be closer to the kitchen. Another option is two rugs in wide runners. Creating a walkway through the center of the room. Still thinking the sofa center of the right window. Just some ideas :-)

#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.
