Welcome to the forum!
Honestly, I think you probably did yourself a favor by going big up front. As these cards age they will make a solid anchor for keeping your AAoA up as you acquire new cards. Also, pretty much all of them are keeper cards that you may have for decades. I wouldn't worry about getting into Chase too much at this point- you have a lot of marathon left and having solid, paid trade lines will help you once you get under 5/24 in a couple of years. Your inquiries will fall off over time, and when they do, you should have been able to grow your current limits a decent amount which really helps with the higher-end Chase cards. They don't like to be the first one to give you a massive amount (I was lucky).
Once you're under 5/24, apply every 6 months for the next Chase card, use it responsibly, and then keep that up until your have the Trifecta (if that's your plan). Judging by your scores, I suspect that you won't have any issues with those when the time comes. I like to keep my HPs under 5 in the rolling two-year window, but that's just me being very conservative.

You can still "work on stuff" during this 2 years.
This here is a crucial piece of advice. I've increased by Discover from $1800 to $8700 in three years and probably sould have done more. My CapOne is bucketed sub-prime, so I've gven up on growing it, but it's a zero AF card that is worth more as aged credit than a daily driver.

... I'm relatively new with 1 year in the credit building world ... I got greedy and turned the marathon into a sprint and got 7 cards in one year before understanding the "5/24" rule. I'm willing to garden for as long as possible now. I would like to ask if anyone has an tips for me moving forward.
Welcome to My Fico Forums! 
Congrats on all the approvals! I agree that you got greedy and moved too quickly but that's all water under the bridge. It's great that you realize that now and want to be more savvy in the future.
Gardening is definitely in order for your profile. I echo the advice above. Most of the cards you've got can grow nicely over time or be PC'd into other cards. You have some good diversity. Letting it all age is next and the 2 years mantra would be helpful.
After that, try not to overdo the apping. It's a long-term stategy, so plan for your apps and try not to do more than one every six months, on average. If you do that, you'll almost always be in a place to apply and be approved for credit if you need it.
I can't tell you the number of times in my decades of credit that I've found on short-order that I wanted or needed to apply for a line of credit. Maybe you need tires or a refrigerator and want to take advantage of special in-store 0% financing because the funds are a little tight. Maybe your car breaks down in a big way and you decide it's smarter to trade it in rather than repair. Maybe things change in your life and you find yourself looking for a home mortgage. (Look at the coronavirus situation now and how quickly life has changed. There are tremendous opportunities to refinance a house now to save money as well as people looking for any way they can to stretch their budgets due to sudden lost incomes.) Plan for the unexpected and you'll always be ready for a rainy day. Use your credit wisely so it can work for you when you need it.
