Turn this small room into office with wall and door

We have this small alcove type of room and would like to add walls and some kind of doors to turn it into a more private office area. How do you imagine the walls and doors (with glass I think) would look like? Should there be sliding doors, barn doors, French doors? Blinds on the glass? Solid walls with doors in center? Would like open concept when not needing private office area thank you!!
