I don't know which powders meter best in the autodisk but I would assume ball powders are best. IMR4198 and Hodgdon Varget (for example) are extruded powders so look into this. Your not mentioning what kind of firearm in .223 your loading for. I load .223 using IMR4198 in a Sabre Arms AR-15, this gun eats anything but not all ARs do. Just so you know IMR4198 is a hot powder for most autoloaders, consider something a bit slower. A bolt action .223 is of course no problem. The Hornady book has a great section on loading for ARs, and there is a website forum, I think its called ar15 dot com you might want to check out.
In my not so humble opinion, you should do yourself a big favor and get 1 caliber under control before the other. Especially considering that one caliber is pistol the other rifle. So holding off on powder purchases for both calibers might be prudent. I think, but would not want to go to the wall on this, but my advice is get your feet wet on 9mm, load and fire successfully 100s of rounds (1000s would be better) before moving on to .223. Both are handloading for sure but there are different techniques to learn. If you handload .223 you will probably need a case trimmer at the minimum. I personally have no good words for the Lee chamfer and deburring tools needed for rifle others my disagree with me here. You need case lube also.
Right now for 9mm the world is your oyster. Powder availability is good. W231 is good and if you see Hodgdon HP-38 it's a bit less expensive and the exact same powder. Other powders to consider and will work are Hodgdon Titegroup, Clays (regular clays), CFE Pistol, Winchester WSF and autocomp, Alliant Bullseye, power Pistol, BE-86 and Unique, Accurate Arms #2 and #5, VV N310 and N320, and Ramshot ZIP. There are others though.
