Casting to Google Cast devices is pretty locked down, but most things that can cast support a handful of different standards, so casting to other things is usually possible.

Plasma Bigscreen doesn't have the functionality natively, but jellyfin-mpv-shim and Kodi can be cast to.

Never could get Kodi to work for me. Guess I'll try out the jellyfin one, thanks for the suggestion. But also, if this is possible, why can't I figure out an easy way to just cast from my phone to my desktop?

From what I can gather, the little cast button is implemented via a google-specific api, and in the interest of DRM, all apps and OSes that show it will only cast content to specific "blessed" devices that are locked down.

If I could run a program on my PC that behaved identically to a Chromecast as far as my and my guests phones are concerned, I would be sooooo happy. Because then I can put that on a raspi and hook it to my TV without having google MITM everything I do.

The jellyfin shim may only be for Jellyfin clients, not for arbitrary clients. I thought it used a generic standard but now I'm not sure.

Kodi is the closest that I know of to what you're asking for but it definitely won't work for everything even if you do get it behaving.
