Self signed certificate (can generate against any domain I need) or utilising a dev specific hostname against a domain I already own, e.g. dev.mydomain.org, so that I can get a certificate most browsers trust out of the box (e.g. via letsencrypt). Then typically I just pass through nginx to HTTP locally, which is typically what I do in prod so the config isn't new to me
