I have a few answers for you.

"Mostly with selecting characters I want to represent my series."

Maybe your problem is that you feel like you NEED to make one. So you pick things that feel forced. Umbrellas are made to be a pet project for the maker, something meaningful. Just pick characters you really enjoy. IDC if it's Mario or blablabla, just pick what YOU want.

"If I just add completely random characters, I have trouble feeling invested in the storyline. But I still want to make the roster unique."

Do not add random characters. If they mean nothing to you, why add them? Never hold yourself to a specific "theme" because are you really a person with only one specific "theme"? No. You should be attached to the game because it represents you. I think you want to make something "perfect" or something that makes sense. Just make YOU.
