If you do be sure to be extra gentle with your furniture for the first month of use.

Oil paint makes a case for itself with its reputation for easy application and a long lasting finish that can be scrubbed and cleaned regularly but latex paint is the best choice for most cabinets since it offers lower levels of volatile organic compounds vocs and is quicker to dry.

Latex paint requires all cabinets to be sanding and primed.
The short answer is that latex paint is best for cabinets.
If done right you will prime wet sand then prime again which is very labor intensive.
Do not apply water based polyurethane over the top of gloss latex and acrylic enamel.
Sanding also requires more materials therefore more expenses.
