In the interest of reducing wear of the chainrings, would it be better to use modern chains designed for 6,7 and 8 speed freewheels rather than vintage chains that were designed for 5-speed fw's?

Since I have about a dozen NOS freewheels, this Falcon will remain a 10-speed (5 cog freewheel) bike as long as I own it.
8-speed chains should work just fine. The important thing is to replace the chain before it elongates too much (1/16" per foot is the rule of thumb.) Do that, and you should get many thousands of miles from the rings, especially if they are a hard alloy like the old Campy rings.

P.S. Specialites TA still manufactures 144 BCD road rings. Snag a couple now if you're concerned about that: https://www.spacycles.co.uk/m2b0s113...-Chainrings-TA
