Ron Price, founder of Healing Harps (Illinois) brought to my attention the occasional need for music that could be played with one hand. The beautiful thing about harp, is that this music is equally suited to either left or right hand, as one's need prescribes. Fingering is the same for left and for right hands.
All of these, with a little adaptation (for overlapping notes) can be played hands together or split between two hands, which is how Ron used these at times for those recovering from traumatic brain injury.
The skill levels required are varied.
There is some difficulty with one handed playing when adding chords. Placement needs to be careful, allowing preceding notes to ring full value for touching the string anew for the next beat. If you're using these resources while one hand is recovery from injury, then take this time to work on this skill. To play legato when repeating a note on a string, you'll end up, literally, playing the note as you play it, so that you don't place-then-play, which creates a moment of unwanted silence between the notes.
Anything you learn with one hand while your "other half" heals, will benefit you in the long run. If you're weak on reading bass clef, then grab some of those options as they are available.
Notated in treble clef (with a few exceptions).
There are a growing number of options with melody in one hand and an very simple part for the "other" hand, for those with arthritis, or other woes that limit use of all the fingers on only one hand.

Away in a Manger - notated in treble clef
This may be played in any octave. If you find it easier to play left hand below middle C, you can transpose by the octave, or use the bass clef version.
Away in a Manger - notated in bass clef, for those using left hand, not wishing to transpose
Away in a Manger for TWO hands, with a very simple right hand part, melody in bass clef
Carol of the Bells (Ukrainian Carol) - There are other versions on this website. This one aims directly at a more dominant left hand and limited right hand use. Take it slowly, let right hand, if necessary, play with only one finger.
