FMLA and PFL leave / W4 withholding

2025 will be much different than our 2024. We purchased a home at the end of 2024 and are expecting our first child in a matter of weeks. We file jointly but in past years we each withheld as single/married filing separately, to reduce how much we owed at the end, since we could only do standard deduction. 2025 will mark the first year we can itemize deductions from mortgage interest and claim child tax credit. My wife will also be receiving state benefits for FMLA/CFRA and PFL for 5-6 months and I will be receiving PFL for 2 months. 

 

What would be the best way for us both to fill out our W4's (possibly DE4 as well,) for 2025? As is currently, after itemized deductions, it appears we will not be owing this year, but we also want to consider our state benefits and would like to be close to 0 at the end of the tax year.
