I just woke up thinking about this; I have looked very briefly at Bottles (containerizatiom for games and programs), and I actually think it claims to do EA/Origin if I remember the screenshots correctly, but that was about a month ago and I totally forgot to look deeper. Still doesn't check off everything but it's still progress if so.

I'm currently latched into windows 10 until eol and I've been trying to switch to *nix for two decades now, but something has always been too much of a hurdle (dog war flashbacks meme of the wifi driver hell of the mid-to-late 00s) and I end up giving up, restoring from a backup and waiting a couple of years to do it all again. It used to be fun, genuinely, but yeah at this point I want someone else to do it these days and tell me what's broken, I just want to enjoy my time these days. Troubleshooting and trying potentially solutions for a few days just to get nowhere isn't the joy of learning that it once was.
