The main reason I would think it's a good choice is because if you decide to get a CA certificate later, you just drop it in and you're done; no additional configuration required.

If you don't have a CA certificate, you're probably not advertising your https:// URLs anyway, so unless search engines are aggressively looking/prioritizing for https transport, it wouldn't seem to hurt anything to run a self-signed certificate there.

HTTPS everywhere. And I would not trust an entire site to go unindexed.

There's a lot more to change if I want real HTTPS support. Changing a single port number is the least of my worries.
