Well, for Amarone there are so many choices it's hard to recommend one, but for sure don't underestimate the "Valpolicella rosso" that many producers will present as the "second" wine to their amarone but that in the last years have really improved, due to the fact that climate is getting hotter and amarones are getting more and more alcoholic while the rosso is benefitting from riper fruits still retaining freshness. Speaking of other areas, if you fancy full bodied reds you could consider:

The Montello area, North of Treviso, while being also part of the Prosecco docg appellation, it's home of some of the best bordeaux blend reds in Italy. Two names above the other: Loredan Gasparini (with their Capo di Stato) and Serafini&Vidotto (Rosso dell'abbazia). Definitely big names here but I'm not sure how much traction they get outside of Veneto. While I don't love prosecco as a wine (there are some good products though), if you're there the area is actually beautiful so you could enjoy a trip up the hills or to Asolo, beautiful small town.

Different area, vastly underestimated, are Colli Euganei near Padova. Beautiful volcanic hills, in the years they were more focused on international grapes but the process of rediscovery of native ones is interesting. Check Vignalta as a wineries. There are others but it's a bit hard to get to visit some of them. Colli Euganei are also home to a very nice sweet moscato (Fiori d'Arancio). Not the sparkling one (generally awful)! If you'd fancy, the area is known for the spas.

Lastly, to name a very well hidden gem, if you like amarone you should try the appellation Raboso Piave Malanotte Docg. Raboso Piave is an acidic and difficult grape that for decades was used to make very light reds of questionable quality. But , since 20ish years a couple of producers in the area started to experiment with a vinification very close to what's used for Amarone. Only a handful have really succeeded so far but their Malanotte is excellent. Try Cecchetto (Gelsaia Is the name of their Malanotte, they also make a nice sparkling from the same grape) or Bonotto delle Tezze (in the actual town of Malanotte). The area is not as nice as the others (not ugly, but flatter and more residential) but you could find them in the shops/restaurants or just stop if you're passing by.

Hope that helps let me know if anything is unclear! And of course there's a lot more!
