You will need to seal the edges, with a shellac based primer because the end grain will absorb the paint, you can use a high gloss acrylic paint, to get a good sheen, and you can always put a coat of high gloss lacquer or polyurethane over it.
To get a smoothest coat you need to spray it, if you don’t have access to a hvlp you can use smooth foam rollers and sand in between coats

I have probably made over a 1,000 MDF raised panel doors and used MDF for case work on built in cabinets for years. The best finish was obtained by using an oil based primer, sand, sand and they spray latex top coat.

Any routed or cut edges may need 2 coats of primer, just be sure to sand smooth.

Good luck-
