Hi @Kevin William Joseph ,
You want to split an item with a multi-choice column into multiple single-choice items.
I found a similar thread for you, please check it out:https://powerusers.microsoft.com/t5/Building-Flows/Split-two-multi-select-fields-in-sharepoint-list-that-are-multi/td-p/1316701
Per my knowledge, you can achieve this function through Power Automate.
In fact we are currently providing help on SharePoint in the Q&A forum, and Power Automate is a product independent of SharePoint which we are not so familiar with. Regarding the difference between these two methods which is more related to Flow, we would recommend that you go to the forum dedicated to flow for more professional help, there will be very professional people to solve the problem for you quickly
