To give suggestions on style you should first consider what you want or issues to address from your window treatments. Such as privacy, light, decorative only, insulation properties, when you use the room etc
The windows do have some issues to consider with a treatment style, mainly the lack of stack back area from the window to the corners of the room, especially if you wanted functional curtains. Curtains made with thicker fabric or lined/interlined treatment requires more stackback area as do certain types of headers styles.
You can have layered treatments to tick various desired boxes - eg keep the blinds for the practicality reasons, and then dress curtains for decorative, softening the room and tie it in with the rest of the room/openplan area.
There are many options and deciding what you want from it (as well as budget) can help to narrow down what to go for.
all the best
