My opinion is you want a jig designed to use with a trim router, not one for a drill press, unless you've got a real milling machine, at least something like a Grizzly if not something nice like a Bridgeport.
Most people are going with the 5D Pro, Modulus Extreme or 80% Arms EZ Jig Gen 3. Those are all basically the same design and mostly vary only in color. All 3 are hard to find in stock. Buy whichever one you can get or pick which color you like best.
You will need one of their specifically supported routers, plus their milling bit. Most people say to avoid using the drill bits they sell because they are poor even for Chinese made ones. Some people have had trouble with soft drill bushings going oval in the 5D jigs, and I don't know if that affects Modulus or 80% Arms sold ones. I would recommend you to get a drill press to do the selector and FCG pin holes just to be on the safe side instead of using a hand drill.
There are not really any other currently sold ones that are really designed to work with a router. I have one of the older Modulus HD jigs, but they aren't made anymore.
There are some other options to convert some drill press jigs for use with a router, but they are a little more DIY because you need to separately source spacers and longer socket cap Allen screws. I've had success doing this with the UFS jig from here:
https://www.uniquefirearmsolutions.com/UFS-80-Lower-Receiver-Jig-p/ufs_jig_universal.htmThe spacers are 1/2 in. x 1 in. x .257 I.D. Nylon:
