Besides the fact that -D is a SOCKS proxy which operates through one port, is there any other differences? Specifically, would there be any differences in terms of HTTPS connections?

The only difference between -D and -L is how the destination server is specified, which you already mentioned. There are no differences for HTTPS; both options provide you a channel for TCP connections without any regards to the data transferred.
