Avoiding using Global Variables

I wish to use a variable within the sheet to run a call back i.e.:

    Output('Holder', 'children'),
    [Input(Generate_ID([UPDATED_VALUE]), 'value')])

however I am trying to avoid doing this with a global variable for reason as explained in

However since the value is already within a callback trying to run a callback on a callback using a hidden variable results in dependency errors (and using app.layout[’…’].value has an issue as described in Values in input not updating).

Would “User-Based Session Data on the Server” be a recommend way of doing this (as described in

Many Thanks
