Adjusting withholding for new job and raise

If my spouse has had a pay increase, I have started a new job, and our benefit deductions pre-tax have all shifted in 2024, what tools can we use to make sure we're not underpaying too much in taxes? I used an online IRS calculator when I changed jobs but not sure if there are better tools, especially now that I have started putting some pre-tax money aside for retirement, etc.
