Most any crankset that has a BB compatible with your BB shell on the bike. You should also consider if the crankset is appropriate to that genre of bike and the number of speeds on the rear as that will determine the chain line that crank will or should give.
Figuring out what the BB shell is made for is your first step. Threaded or press fit, shell width, diameter and etc.

A simple measurement will tell you all you need to know.
First eyeball to know whether it's threaded, then measure width.
Odds greatly favor a 68mm, 24 x 1.37" standard BB. If so pick whatever BB and crankset you like from the many available. If only buying the BB make sure it matches your crankset.

If it ain't broke don't fix it. Does look so bad that you think it's hideous?

The frame will accept nearly every crank available. The current Campagnolo Veloce(?) bottom bracket may not work with much of anything. Which are you trying to fit to? And what kind of crank would you like?

On top of that, the inter-chainring spacing on these Campagnolo cranks is different from the Shimano/SRAM standard. Unless you're also planning to swap the shifters, derailleur, cassette, rear wheel, and chain, leave it alone.

Bianchi Via Nirone from 2006
likely 68mm threaded as thats what most roadbikes had at the time.
bianchi were allowing for english /bsa 68mm a lot
you can put shimano / campag on it.
just match the bb to the cranks. egs. shimanos have square taper, octalink, isis

That's because later Shimano cranks have wider spacing than standard. 10 speed Sram, Campy and Shimano were the same.

um,
twice people have guessed the width to be 68.
Italians were famous for using 70MM

But you never know, and hopefully the OP looks for markings or dimensions rather than just taking our word for it.

I put a Campy Centar Ultratorque crank on my 1982 Bianchi. Got it close out cheaper than replacing the pair of chain rings on the original Sugino crank. When I swapped out the Bianchi frame with a Tomassini frame all I had to do was buy some Italian thread bearings to replace the BSA threads on the old frame.

That is elegant in its simplicity! The Dura-Ace crankset looks like someone's idea of a 23rd-century spaceship part.
Not as light as the Record, but to my sensibilities this triple looks less massive than the Dura-Ace double.

This is a no brainer to me you have a threaded BB. Could be Italian threaded but I doubt it, and in any case you just get the correct Shimano bottom bracket. In my book Shimano has it over everyone on hollowtech cranks and external bearning bottom bracket. A simply R7000 crankset with BB60 bottom bracket and you will install and forget about it except that it will perform and work with the best. I have always said that Shimano Cranks, chains, and cassette simply work with the best for sure. The front shifting in particular.

There was and is nothing wrong with any of the previous crank types - ramped and pinned chainrings are old news.
Of course, we have no idea what the OP is trying to accomplish. The crank on that bike is decent.
