All we got was a half assed copy\paste of the same ship over and over. Since when has the federation ever had that many identical ships deployed at once? It's usually a smattering of different designs. i think everyone was expecting the Enterprise to show up as well, but nope.
Another member thoughtfully posted about modern HDTV & 4K and how they cannot get away with makeshift model designs anymore. They re-used models over and over again...ships and starbases alike.
But I had another thought or explanation as to why the sheer number of identical star-ships (to cover up the lack of money/time/imagination)
After the huge losses to the Borg (Nemesis 2373) and the Dominion (DS9 2371-2375) Starfleet had lost a large portion of the fleet and possibly quite a lot of older star-ships.
In Picard (2399) they had just over a decade to build new star-ships, before the attack and destruction of the Utopia Planitia shipyards (2385) which then stopped all production.
Its also possible that Starfleet built and used the same lineage of star-ship to make up the numbers very quickly at an alternative Federation planetary site (so about 14 years between the shipyard attack and the events in Picard). Other star-ships designs meanwhile may have been retired due to their age (Enterprise E Sovereign class would already be over 25 years old).
Alternatively given the copy and paste approach to the fleet (headed by Riker) perhaps the Federation has replicator technology which is so enormous and sophisticated that it can replicate an entire starship...
