Found some interesting display information on the USS Enterprise in DIS:"Brother".
Interestingly it lists the crew complement as 428[?]/430, whereas the dialog said something akin to all ≈250 were accounted for... The ships length isn't listed, but her nacelle length is, looks like 153.6m, which would make her total length (based on some fan model renderings based on the angles we saw in season 1) around 300m. Her cruising speed is also listed as warp 6(384c[?]) with a max of warp 8(512c[?]).
We also get some more volumetric information amusingly as another listing of the ship's Gross Tonnage: 100,000 Mg. This is in contrast (and more reasonable than) Scotty's statement of nearly a million metric tons.
EDIT: Trying to fix image host.
