I’ve always just slopped on joint compound, sanded it smooth and then painted the edges, but I’ve heard there are multiple ways to prep the edges of MDF board before priming and painting. What do you guys normally do?

MDF can be had in different grades. The best will only require primer. Others may need the filler.
Inspect it before you bring it home. BORG stuff usually requires filler.

one of the best MDf, edge sealers is BIN by Zinnzer , it is a white primer and shellac based , i usually quick sand the edge with some 320 just to cut bown the fuzz, then apply 2 coats of the BIN, and scuff sand with some 320, the shellac based primer seals super well, for a clear i use seal coat, also shellac based, most of the box stores carry it, i know Lowes does…
