Oh yes, the new blocks and features are probably one of the main reasons why Cube is updating to the 1.19 version of Minecraft. I mean if we look at most of the other servers they are stuck either in the 1.8.9 version because of the combat changes or in 1.12.2 since that was the last version before Mojang changed quite a lot regarding the server code. With Cube updating to such a higher version they will be able to include many features as well as blocks that just aren't available elsewhere possibly appealing to a whole new community of players.
And yea, that includes brand new maps and utilizing them in different environments and games. If you haven't go watch the 10th-anniversary trailer as my fellow Minemans before me already suggested and I'll also put one image here for everyone's viewing pleasure and excitement of the update! Also yea, I think getting a map specifically in the 1.16+ theme is very likely.
