PLEASE don;t think I am trying to be snarky here. I'm not. I just really do not understand why, when people have lovely adventitious roots on their cutting like you have, you think that there is a need to 'root it' further. There really isn't.
If you just plant the cutting in a loose well draining mix with both of those roots under the soil, it should start to root and grow. It may take a while. The adventitious roots have to get the message from Monstera central that it is now their new job to make some more roots, and get the plant started. But they will.
You don;t have a lot of tissue between your cut end and your first root. You should treat that with a good fungicide (NOT cinnamon) and pot that up in a small container. Don;t drown it. Just keep it evenly moist. And don't get curious to see if its rooting and pull it up after a week. Just to check. It takes PATIENCE.
Water rooting attempts will only screw this cutting up, IMO
Monstera are what are called 'primary hemi-epiphytes'. They do not begin their lives rooted in the ground. They begin life as total epiphytes when a seed germinates on a host structure. They have the ability to NEVER have a trunk that grows from out of the ground. If you leave the cut end of your cutting out in top and lay the cutting sideways so the roots go into the soil, it might be even better than planting the cut end under the soil.
