Three feet would allow for a narrow bench and a mirror above could also be handy.

Not every wall has to have stuff on it.

If you actually had more guests staying over, then I would suggest something like a flat/thin wall mounted Samsung Frame TV, as some people like to watch a bit of TV before going to sleep.

I think a large piece of art would look great on that wall, but I wouldn’t put a table underneath it. With only 36 inches between the bed and the wall, leaving the floor clear will make the room feel more spacious.

I’d choose one large artwork with a little color and then repeat one of those colors in a pillow or throw on the bed. That would make the room feel finished without adding more furniture.

I recently put together three very different bedroom transformations that might give you a few more ideas for adding character to the room:

I would place various pictures on that wall while removing pictures from the bed wall. The purpose is to let the bed wall to be clear, supported with the lamps lights only that modifiehs the depth of the space letting it to be clear. I know how difficult it is to let the wall empty. But its crucial for the overall atmosphere. Otherwise to have burden on every wall brings heavyness.

I suggest a landscape wallpaper mural that covers the whole wall.

Nice room but a few tweaks will make it even better.

The greatest luxuries in a guest room are space and a quiet dark place to sleep.

7 pillows is too many, they take space that your guests will need. Where will they stack them?

No more furniture. A comfortable walkway is a minimum of 36", which you have.

The blinds have too much light leakage for a bedroom. Add a light blocking curtain that stacks to the right of the window, and draws to the left. Nothing else on that wall.

Move the woven wall hanging to the wall you are asking about at the foot of the bed.

I think your pictures above the bed would be more attractive if they would "read" as one piece of art. So hang them level, and group more closely.

“With only 36 inches between the bed and the wall, leaving the floor clear will make the room feel more spacious.“

Wise words.

I like @SD’s suggestion of a landscape mural - to cover the whole wall; or, alternatively, maybe just a simple wallpaper - or even a very simple design done with a stencil. I would not do art, per se; if I were a guest - I would not want to be in the bed staring at somebody else’s art choice, directly in front of me. A nice landscape mural there might add a bit of a relaxed vibe. Wallpaper is also very personal and taste specific... So you would need the right mural or wallpaper. It would be easy enough to just do a subtle pattern with a stencil, to give the wall a bit of texture and interest. Then, if you notice that your guests appear to be shell shocked 😳 and you suspect the stencil wall - it would be easy enough to paint over it. :)

There are so many possibilities. You can look on Etsy.com for stencils.

For this effect, you could paint the wall an ivory/cream type color - and bring in the beige on the pattern.
