Do I not get reward points if I pay in excess?

I have many cards and I have made it such that all of them come due at the starting of the month right after pay day. But since the bill is generated on 17th of every month for all of my cards, I don't just pay the dues of the last billing cycle, I pay the total outstanding amount, including the transactions I have made from 17th to 30th of the month.

So, do I get reward points for the transactions I made from 17th (Bill Generated Date) to 30th (Bill Payment Date)?

Also, if I were to pay much more than what I owe in the bill as to make up for next month's spends as well, does it negatively effect anything?

I am trying to financially responsible and having a clean slate at the beginning of the month and having some money I can't access would help me do that.
