@ShiroKuro When our violin-playing daughter was young, I used to arrange music to play with her, pieces by Dvorak, Prokofiev and Ravel, for instance. I would reduce or omit the melodic line in the piano and write out a violin part.
Conversely, since I play the cello, I would rearrange the piano parts to cello pieces (so she could accompany me) such that they were simpler than the original. In this way we played "The Swan", and Gounod's "Ave Maria" (with the Bach C-major Prelude, simplified), among other things.
If you want to play with a cellist, investigate pieces by William Squire. They are not particularly difficult for the cello, and often the piano parts are fairly simple as well.
I know that there are other books of short pieces for cellists and piano accompaniments are often not difficult.
Lastly, there's no reason why you have to play everything that's written; you can simplify what you see on the page (within reason). It's a good skill to develop.
