Polyvinyl acetate (PVA) primer over the drywall and taped up parts. It’s cheaper than KILZ. It is only a sealer for the paint. One coat. Then, a personal recommendation: Flat white: no tint, no shine. This is because you don’t want glare (specular reflection, also known as shiny spots), or to look at crappy taping work if it is present-shiny shows that up. Scrubbing isn’t an issue in a woodshop, dust is, and if you want dust it off, you can vacuum it. Flat white paint requires less lighting, leading to reduced electrical costs.

Note: paint is NOT a primer/sealer, each serve a different purpose. You can paint to your heart’s delight, but one coat of PVA type sealer will give a good base for you final coat.
