Find Text/Value & Use Found Cell, Row, Column In Macro Code

I am trying to clean up and simplify my macros by compartmentalizing frequently repeated commands. I like to search for text in column headings and define the cell containing it as a range that I can later use .column or .row commands on, so my macros are a bit more flexible. The code I currently use for this is

Dim XColumn As Range ‘the cell containing the text “X”
Cells.Select
Selection.Find(What:="X", After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False).Activate
Set XColumn = ActiveCell

I would like to be able to create a Macro (possibly name FindSetCell()) that will accept arguments and achieve the results of the above code in other macros
I think the command might look something like FindSetCell(“text to be searched for”,”name of newly Defined Range”) But I have not figured out how to code it
