The best information is that which is revealed by events. The Ukrainians have a remarkably good track record vs Russia over the past year.
Russia in theory should have a massive overmatch vs Ukraine on all fronts, from tech to materiel to the institutional military to just plain cash. But Ukraine has managed not only to resist them but to roll them back.
That outcome should inform us of many things.
As for the Pakis, one thing they did get was the look-down-shoot down capability, plus AMRAAMs. That is exactly the most likely use for Ukrainian F16’s, as a supplement to the Ukrainian S300 SAM systems, on which so much depends. The same F16 models are being retired right now by Norway, Denmark and the Netherlands, being replaced by F35’s. Those are the most likely source of F16’s for Ukraine.

Except for the ones that had to runaway because they have no ammunition. Except for the 16 and 60 yr olds being conscripted to fight.
They have what you call a good track record, only because they’re being propped by the US and NATO….and the only people suffering and dying are the Ukrainians while you’re sitting in the comfort of your home in the USA, cheerleading more death and destruction.
