Splatoon and PKMN are
teeeechnically fighting games in their own sense. PKMN being a turn-based strategy fighting game. I mean, you really cannot say the part of the game featured at APEX is not a fighting game. It's Pokemon BATTLING for goodness sake. Sure it's not a traditional fighter, but it's still a fighter in it's own sense.
Splatoon is also a combat based game, (or a paint the sh*t out of everything game i think i don fuggin know).
It's got guns n junk in it, so there must be some element of combat in there, so it's existence at APEX is also reasonable.
