Big improvements in selecting block elements when nested in other blocks, including layout solutions by third parties as well.

Grouping/ungrouping looks good but we need padding and margins in the group, columns, and, perhaps other blocks, to make them a viable option for layout. And, maybe a drop down to designate the block div as either section or one of their syntactically correct designations.

Block suites like Kadence blocks make the above redundant. This adds to the standardisation issues. There is this vacuum with the lack of proper layout functionality built in to the editor being filled with various third party solutions which can’t be swapped without breakage.

Proper built in layout structures/blocks that allow third parties to hook in their own UI and features could solve this.
