Ready to Plant?

My monstera cutting has been in water for 5 months. I’m wondering if it’s time to put it in soil and what size pot should I put it in? I have both an orchid size pot and then something bigger like 6” width x 8” height. How deep should I plant it? Should I untangle the roots before planting or leave alone? Does it matter which direction I plant it in? I’m not sure what this yellow ish thing is towards the bottom of the stem.

First time with a monstera so TIA for answering all my questions!!
