No. The prefix for apache is LOCALBASE, otherwise apxs won't be found.
You don't really have a choice here, and custom configurations (tweaking
parameters not tweaked by the port) are beyond the scope of the ports
collection.

Yes. You disable basic features of the ports collection. I can build the
port with a different prefix to check whether the packing list is
correct, or add the package to a scratch area to examine its contents.

There is. Of course they are only recognized by the http server when
installed in its module directory, but perhaps I don't want to do this.
People tweaking PREFIX normally know what they want, and thats not
always that `things just work', even an user with average experience can
guess that when you install modules with a different PREFIX that you web
server, they won't be found (at least this is what I would expect). Most
of this stuff relates to packaging, a similar example is PR 66032, which
assumes that stuff is installed in a clean tree to be packaged. Which
reminds me that we should honor this scenario in the apxs patch.
