Shove is still a bonus action.
You can see it in the hotbar during PFH.
To be honnest about bless I think it is more of an AI issue than anything else. IIRC when the AI use magic missile all projectiles hit the same target. In my mod that changes bless so you cast it like you cast MM, the AI seems to not use bless/bane anymore.
I may be wrong about that though.
