ISSF reamer is what you are looking for I believe

PTG makes a .223 ISSF Match Rifle chamber reamer w/ .169" FB. I use this chamber for 80's up to 90s.

IMHO, Go short!! You can always go longer. You want to be able to get "close" to the lands.
Nothing worse than finding your load at an OAL then the throat wears, and it will, and you'll have to start all over again.

I wouldn’t go any shorter than the ISSF reamer. I’m about to buy a uni-throater because my 0.090 FB is way too short even for 69smks to be optimally seated with boat tail above n/s junction.
Modern bullets don’t need to be close to the lands to shoot. And with a nice tight FB diameter, it can be plenty accurate.

I am jumping my 90s by .040"-.045"with good results.
