Indeed : I did some lower level (albeit trivial) TeX programming at some
point, but not recently -- that might explain why I thought the problems
had disappeared. Another reason is that I had changed the syntax class
of backslash character in my .emacs (I made it ".", i.e. punctuation),
which explains why I use C-M-f (but that doesn't address most of the
points you raised).

In order to move by token, I made one further change this morning in my
local setup:
(modify-syntax-entry ?\\ ". p" LaTeX-mode-syntax-table)
which lets C-M-b skip the backslash ("p" here means "prefix").

C-M-b C-M-k would work with the above modification. Not exactly "one
keystroke", indeed, but close enough for me.

To work around that problem, I write this:
\paren{foobar} or \paren*{foobar}
which gives (foobar) (Starred version says to adapt height to the content)
It's as simple as loading mathtools and having
\DeclarePairedDelimiter{\paren}{(}{)}
in the preamble.
