I agree, 99% chance your knee is too far forward as you pedal. As to stem length and... have to see you on the bike.
By the way, the UCI has a rule that the saddle needs to be no closer than 5 cm behind the bottom bracket- this is a curious rule, lots of ways to work around it, but it was written at a time where this saddle was King.
No idea on saddle height either.
People are all over the map in proportion and flexibility.
I see most often out on the road, guys with the saddle too high, cleats adjusted wrong so their knees swing out and in while pedaling and guys with their arms locked.
Can't save them all.
When I catch them at a signal light, I do ask the question that comes to mind from what I see:
arms hurt?
or saddle bother you? back hurt? knees give you pain?
Always without exception, "how do you know?"
