multisite 2-way user profile sync

Let me start with bear with me. I run non-profit and try to save every penny I can so we can give to charity at te end of the year. I am NOT a programmer, designer, or anything of that nature. I don’t think I have had a class in such an area since elementary and earned DOS. I basically sit and figure it out. After a plug-in demolished my site though “I’ll just try it” is out the window!

I have several sites in my multisite network. I want 3 of those sites to sync user meta data if updated on any of those 3 sites. I have MANY customized user fields. I am not using Buddypress as it is not as front-end user friendly and back-end customizable as Ultimate Member. After some research here is the code I have put together (I am reducing this code to just 3 of the fields out of the 40 I have in reality for purpose of this post. I am trying to figure out first if there is something that I am sure many may see as obviously wrong and 2) if I am supposed to put this in my wp-settings file or somewhere else.
