I played around with this a bit, and it seems to work very well, and
quite naturally.  So I've applied this to Emacs 28.

Noam made the suggestion of making this a list of values like (word
paren) instead of word-or-paren, and that does seem like a good idea,
but either works.  I guess somebody might want (word punct) and not
word-and-paren-and-punct, for instance?  So if somebody were to change
this to work that way instead, I wouldn't mind, but I think it's
probably fine as is.
