Do I need to remove the defaults in order to make the noexec for /home work? Would I need to also add the rw and some other replacements to it that are normally included.

This is a webserver.

You don't need the defaults. It's a "noop". You can add the specific options you need without specifying defaults.

The only use of defaults is... as a default. If defaults didn't exist, how would you specify "no options" if consecutive spaces are treated as a single one? (Without '')
