Just pay your bills on time. That's all you need to do. All the tricks you see here for maximizing score are really not needed mo, unless you're planning an application for credit. I get that there are benefits to keeping your credit in the best shape possible, but micromanaging is not for me anymore. And build up a savings and investment portfolio. My savings wasn't enough after an emergency trip to the hospital and now I'm rebuilding in my late 30s. All those years of great credit didn't do squat for me when I couldn't pay the bills.
That's my advice. Good luck with your credit journey.

You are already doing excellently!
Just PiF after you get statment, don't worry too much. People doing AZEO usually pay all but one card in full before statement cut. You still spend on the card, lenders still get swipe fee, you just don't have a balance on the statement.
For the long term, consider diversify the lenders.
If you want to max reward soon, consider get into Chase system earlier since they have that 5/24 rule. Try not to app too many cards in short period of time. Get 1 or 2 per year would be alright, think carefully before applying, only app for those that makes good sense.

Congratulations on your new card. As you've recognized, Discover is a great card to use during its first year.
As the posts above state, you don't need to pay interest if you wish to cut a positive statement balance. All you need to do is pay the statement balance by the due date, which is about 21 to 25 days after the statement cuts. Any new charges made during the month won't become "due" until another statement hits.
If you'd like or if you see the need, you can pay down your new charges before they hit your report. Doing that can potentially avoid situations like having 97% utilization reporting. Most cards (like Discover) report the statement balance on or soon after the statement date. Others report on a different day of the month. US Bank is an example; they report the last day of the month. If you haven't done so already, you'll want to confirm when your CU card reports.
As far as reports and scoring go, my only suggestion would be to try to have your Discover card report utilization of 28.9% or less. From the standpoint of your report, it's a good look. From a scoring standpoint, there's a big difference between 28.9% and maxed. If you miss that mark occasionally, don't worry about it. As you know, your score will rebound easily.
In your case, I'd look at things from a budget standpoint. I'd pay as frequently as necessary in order to keep a reasonable amount of your limit available for new charges. And I'd keep 28.9% in the back of my mind when the statement is about to cut.
AZEO (all zero except one) has been mentioned. That's when you report a small positive balance on one card with the rest reporting zero. Implementing it is a good skill to understand. But you don't need to deploy it right now. Plus, it's a chore when AU cards are involved.
Once your balance updates, your score will be safely in the 700s. That's generally plenty for a credit card application.
