You can't port an employment-based priority date to family-based or vice versa.
You don't necessarily have to forgo the employment-based green card to pursue adjustment of status on the family-based one. You can file the family-based AOS and have both that and the EB I-485 pending at the same time, then get the green card based on whichever one reaches the approval stage first.

They are both over 21 but currently have EAD under my pending employment based I-485.
They would be in F2B if you file I-130 for them, not F2A, since they're already over 21. There's a wait of over 8 years for F2B to become current.
If the date is current, how long does it take after I file for my kids to get their green card under F2A?
