It's quite common for the selection created by motion to have immediate subsequent use. I do use the ';' or ' ' commands to clear the selection or end multi-selection, but typically only once per major operation. On top of that, it is common to start some new editing sequence which automatically resets or extends the selection in a natural way.
Multiple selection has surprised me in its usefulness. It took a bit to get used to multi-step operations (select, then move/expand/match, then modify, etc.), but the beauty of this is that it's possible to incrementally undo these steps, unlike having to get the whole thing right in one go in vim. I find myself using regex captures in multiple selection -- another example of how I confidently use basic kakoune functionality where I used to rely on recorded macros in vim.
