The problem with the P32 is that it only works for the current tax year, and unless your accounts year matches with the tax year it will only be able to provide part data.

For our year end (which ran 01/08/20xx to 31/07/20xy) we used:

Payroll Summaries

Ensure the criteria excludes nobody:  ("current year" means "current tax year") and use

Reports>>Employee>>Payment Summary History Part 1 - By Date (PYSMHSP1B)

but you could use by Employee (PYSMHSP1) if you'd rather it was ground by employee by date as opposed to by date by employee

Pension Balance owed

The above gives the total employee and Employer contributions taken.

From your accounts you should have the balance at the start of the year in your pension liabilities.  Add the totals above to the liability, subtract the payments made (in your accounts pension liabilities) and the result should match the pension liability at year end

Your pension providers may have reports which confirm receipt of the monies.

PAYE

The above report gives the PAYE owed, any Student loans owed, Employee and employer NI and can be reconciled against the accounts as for pensions

You can get the relevant months information from your HMRC login portal which can provide a summary of each pay month charges and payments made against them.
