Mentioned elsewhere in the thread I think but not in a direct reply so making sure you see it, Lutris has the game specific scripts but also ones to set up environments for Origin/EA App. I’ve used those before with Sims 4 with both several expansion packs and some custom content.

I’ve been using EOS for about a year and a half, and for the year and a half I used Manjaro, and this is spot on. EOS is just a better experience, plus they’ve got much cooler default backgrounds!
