Maybe you should rephrase your question?
Do you mean that you want to replace Sheet1 with INDIRECT and a cell where
you put the sheet name?
Assume you put Sheet1 in cell A2

=SUMIF(INDIRECT("'"&A2&"'!$C$3:$C$258"),$A3,INDIRE CT("'"&A2&"'!$F$3:$F$258"))

I have several working worksheets with data.

I made an summary sheet for all working worksheets.

The formula I used is =SUMIF(Sheet1!$C$3:$F$258,$A3,Sheet1!$F$3:$F$258)

Now, I attempt to replace "Sheet1" with function INDIRECT.
