I like your wish for a dynamic approach! That’s also how I roll 
In that case, you can simply use the Jump & Stop Jumping nodes to make your AI jump, and also make sure it’s air control is set to a high value which you can adjust from the character movement component’s details window. (And yes we could also use a different movement mode to avoid this but where else are you gonna use air control for your AI right?) Then, activate an Add Movement Input node for the duration of the whole jumping process and insert your AI’s forward vector into that node’s direction pin.
Now the last step would be implementing some calculations to make your AI jump correctly but you mentioned you’ve already done that. So this should be it!
Try this out!
