Comparing hypothetical wet navy ships might help:
* a roughly 50,000 ton battleship has 3 medium batteries (3 turrets with 3x 16" cannons), 1 secondary battery (4 turrets with 2x 8" cannons), and 2 tertiary batteries (10 turrets with 2x 5" cannon and 40 rapid fire 40mm autocannons)
* a roughly 15,000 ton heavy cruiser has 3 medium batteries (3 turrets with 3x 8" cannons) and 3 secondary batteries (8 turrets with 1x 5" cannon, 20 rapid fire 40mm autocannons)
* a roughly 5,000 ton heavy destroyer has 6 medium batteries (3 turrets with 2x 5" cannons and 12 rapid fire 40mm autocannons)

each ship is devoting 30% of its mass to weapons, but the battleship has more cannons than the cruiser and destroyer combined and it has bigger cannons.

the key point is that tertiary batteries on small ships may end up being too small, so where a large ship can use a tertiary battery to mount 30 weapons, a smaller ship needs to use a medium better to mount 3 weapons of the same size. If you expect your opponents to have 40 dDR, you want 300 MJ beam weapons to penetrate, and a SM +9 ship isn't going to mount a secondary battery. It will have a medium battery with 3 weapons, while the SM+11 ship it's escorting will have a tertiary battery with 30x of the same weapon.
