How to draw and label a diagram to use repeatedly

Question

I have following format,

And i wish to use that format repeatedly in my document but the label and text in those diagram will vary each time. I searched and found about \newcommand but not able to integrate the diagram in that code. And how to implement the arguments.

code for this diagram is,

\tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt        

\begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
%uncomment if require: \path (0,300); %set diagram left start at 0, and has height of 300

Any guidance is appreciated.

I took the liberty to rework the code of your diagram and to define a pic environment. Feel free to modify all the dimensions in the styles defined to suit your needs.

\documentclass{standalone}

\usepackage{tikz}
    \usetikzlibrary{positioning}
    \usetikzlibrary{arrows.meta}
    
\tikzset{%
    myrectangles/.style = {%
        rectangle,
        draw,
        minimum width = 2.5cm,
        minimum height = 1cm,
        rounded corners = 2.5mm
    },
    mycircle/.style = {%
        circle,
        draw,
        minimum size = 1.5cm    
    },
    pics/mydiagram/.style n args = {9}{%
        code = {%
            \node[myrectangles] (center) at (0, 0) {#1};
            \node[%
                myrectangles,
                above left = 1cm and 1.5cm of center
            ] (north west) {#2};
            \node[%
                myrectangles,
                above right = 1cm and 1.5cm of center
            ] (north east) {#3};
            \node[%
                myrectangles,
                below left = 1cm and 1.5cm of center
            ] (south west) {#4};
            \node[%
                myrectangles,
                below right = 1cm and 1.5cm of center
            ] (south east) {#5};
            
            \draw[-Latex] (north west.south east) -- (center.north west);
            \draw[-Latex] (north east.south west) -- (center.north east);
            \draw[Latex-] (south west.north east) -- (center.south west);
            \draw[Latex-] (south east.north west) -- (center.south east);
            
            \node[%
                mycircle,%
                above = 0.2cm of north west,
                label = above:{#8}
            ] {#6}; 
            \node[%
                mycircle,%
                above = 0.2cm of north east,
                label = above:{#9}
            ] {#7}; 
        }
    }
}

\begin{document}
    
    \begin{tikzpicture}
    
        \draw pic {mydiagram = {text 1}{text 2}{text 3}{text 4}{text 5}{text 6}{text 7}{text 8}{text 9}};
        
    \end{tikzpicture}   
    
\end{document}

which yields:

If there are nodes that you're sure will never contain any text, you can remove the arguments in the definition.
