IDK if this will be helpful to anyone else but I've been making a doc of all the rental codes I come across so I can search by pokemon. It's mostly taken from Victory Road but I also add any particularly interesting codes I find on twitter or youtube or discord (with a link to the source).

I made this doc "anyone can edit" so people can add more codes if they want. Please do not add anything from behind a paywall (like exclusive patreon codes of anything like that) and please credit whoever made the team.

Mostly I've been using it like ... if I need an EV spread / moveset for a mon where I might not trust pikalytics (like say, a Prankster Thundurus) I just search here and check the pastes. I wouldn't copy it exactly but its a good starting point when I take into account what the pokemon does for the rental team vs. I might need it to do. I am still a pretty new player so it helps to have a reference.

Hope this is useful! Also if anyone could recommend a better site to host this on than Google Docs I would love to move it. Ideally something where people can post links as comments on a searchable page. I tried using youtube but peoples' comments wouldn't show up. I think they were getting filtered due to offsite links and long chains of alphanumeric codes.
