Final baby- have to get it right!!

This will be our 6th and final baby. We only have 1 boy so far and 4 girls. If this one is a boy i feel under more pressure to get the name perfect than if it were a girl as we've used up all honour names on our daughters already so itd be simply a case of finding names we like. With a boy im torn between using honour name(s), names we LOVE as its our last so why not love it, using a mix of honour and ones we love but then risking it not "flowing" or having a mismatched first to middle name. Examples of names on the list Honour names Albert (Bertie) James Cillian Kai Matteo Oliver William Joseph Names we love (very random assortment!) Maverick Onyx Leonidas River Atlas Carter Maddox Seamus Ossian (osh-ann) Cairo Jett Rio Rhodes Sonny Bodhi Andre What would you do? Which would you pick??
