In the newest snapshot (have not checked other snapshots) the NBT data for showing what tab a boat is in is different for oak boats with chests and bamboo rafts with chests. These two boats say that they are in both "Tools & Utilities" and "Redstone Blocks" while the other boats with chests are only in "Tools & Utilities"
Steps to Reproduce
open MC Java edition v 1.19.3 pre-release 2
open creative inventory
look at the boats with chests

This is working as intended:
Only weird thing I see is only 1 type of the wood items, buttons, doors etc, are they in the building blocks tab?
Yes they're in the building blocks tab, ones here are only displaying variants with functional difference

So the reason is that the rule for variants in the Redstone tab is that variants should only be present if they have any functional difference. For Rafts, it is a very small functional change, but the reason they're still there is the seat position of passengers is higher.

That's correct. Only the oak version is in redstone blocks; all item variants which were identical in behavior were removed from that tab.
