Yes - I guess that anchoring this regex at a point where it will always
match anyway, will do no harm.

Yes, that should do what you describe.

Note that the . is a metacharacter for "any one"; if you really want
the five-character string ".html" at the end of the request, you should
escape the . to \.

Testing and measuring might show that "return 404;" is even cheaper than
"internal;" in the cases where they have the same output. But if there
are cases where the difference in output matters, or if the difference
is not measurable, then leaving it as-is is fine.
