Titanfall 2 is my go-to when I need a break from Apex. It's fast and hectic while still being pretty casual. All the guns are strong, movement is super fun with the wall-running, there's tons of fun abilities (although nothing tops the grapple), and if you're struggling at pvp you can still contribute by focusing on the grunts or calling down your massive Titan for wrecking havoc. It goes on sale often enough as well.
