I have two gaming groups, one inherited (willed to me, in a way) and one being my "home" group. Recently they made characters for 5e and Troika! Numinous Edition, respectively.
The D&D party consists of a human fighter, human warlock, orc barbarian, half-elf rogue, and tiefling ranger. It was decidedly less-cringey than I had anticipated, though in fairness I did ban all races from outside the PHB, dragonborn, and drow. (I did allow full-blooded orcs, so don't say I never gave ya nothin'.)
The Troika! party consists of a Yongardy Lawyer, a Void Squid, and a Rhino-Man (actually a Rhino-Woman, but the player decided that outsiders can seldom tell the difference.) I wanted to stick to just the rulebook, but my s.o. jumped the gun and rolled up a character using a program that apparently incorporates 3rd party background. Troika! being what it is, I find I'm less concerned with allowing non-core elements into the brew.
What's weird, to me, is my different tolerances in the different games. With the D&D crew, I found myself breathing a sigh of relief at having a fairly "standard" party. I couldn't help but note the tactical composition... oooh, they don't have a healer and barely have any magic at all, but they've got plenty of combat characters... etc.
Conversely, I'm glad that the Troika! squad avoided rolling up some of the more vanilla* backgrounds like Burglar or Questing Knight. (Okay, they are vanilla relative to most of the other backgrounds in the book.) I have virtually no idea what the party is capable of (aside from a vague notion that the rhino and the lawyer are good at fighting), and I'm largely unconcerned as to how this will affect their adventures.
*I actually love vanilla as an ice cream flavor ¯\_(ツ)_/¯
