Northern Italy Roman sites - Aquileia worth it? Others?

Haven't been to Aquileia, but my top two major Roman sites in Northern Italy I have been to are in Verona and Brescia.

Verona famously has the Roman Arena and Theater (both still in use) and a sprawling archaeological museum attached to the museum that runs through various old religious buildings and in interesting. The collection is small-ish for a full fledged museum but has a surprising amount of pre-Roman Greek and Etruscan collections. (This is where I learned of the Etruscan fascination with Hercules which obviously passed to the Romans.)
The restaurant in Palazzo Manfi has some really good glimpses in the underground dining rooms but we only got to see those with a guide on a tour.
Verona has a glimpse of Roman ruins in town but unfortunately the big underground ruins - also has hosted photography exhibits - since before lockdown for restoration work on the buildings above. Verona was the Roman town guarding access to the alps but was levelled by earthquakes in 1117 so the buildings are "new" - aside from the arena, theater and bridges - and the Roman ruins are 20 feet underneath the city.

Brescia has some amazing preserved Roman era temple you can tour as well as fallen aren and then the big museum in town has great artifacts and the basement has in situ mosaics and the walls are old Roman walls.

Bologna's archaeological museum is interesting and worth visiting. It has a heavy Celtic influence since they were a lot of the pre-Roman era and a surprising amount of Egyptian material. But if you keep pushing into the museum it gets less and less organized and eventually becomes a 50s feeling era of old signs and just piles of finds without too much signage. It really feels like the original archeologists complete collections of finds.
There is a brief glimpse of Roman ruins in the basement of the library building on Piazza Nettuno which is worth a look.

Aquileia is pretty, particularly the mosaics in the church but the area where the Roman mosaics and ruins are located is very small. At one time it was an important Roman port but now is inland. I don't think you need a whole day there, just a few hours. The day we went there we visted the walled star fort town of Palmanova, then Aquileia, then went to the coast to see Grado, all three are on the same route. Aquileia could be combined with a visit to Trieste as it is not far and Trieste is a very pretty city with much more to see. I visited Trieste last year and one of our stops was San Sabba Rice Mill National Monument and Museum, a WWII German concentration camp in a converted rice mill.

From Bologna have you considered a visit to Verona? Verona has the Roman arena, an ampitheater, a good archaeology museum and Verona itself has lots to see and do,
For WWII sites, maybe a visit to Salò on Lake Garda or Borgo a Mozzano.

Can't believe I forgot to mention - if you have time in Ravenna and are also interested in stone floor mosaics don't miss the under-advertised "stone carpets" site.
