Figuring out where to go(and where I am) in my credit card journey

Currently 19 and 4 months, I had a 760 credit score which fell to 750 because I just recently got my Amex gold card, aside from that I had my first card which was WF 2% Cashback right when I turned 18, 6 months after I got a credit union credit card to begin building a relationship with them for the future, and now hold my third which is the Amex which I’m hoping to help lead me into the points system, I’m keeping my other 2 cards open off the fact they help due to time opened as well as help build relations. In venturing towards this new points system because traveling is certainly something I have planned for the future what could or should I aim for next and how soon? I have my Amex gold for all food related stuff and split current everyday spends that Aren’t covered on my 2 other cards, but I’ve seen a lot mentioned about catch all cards and wanted to know if I should lean into that now as well. I’ve seen lots about the Venture X for example and perhaps mights qualify, but unsure as to whether there’s others I should get first etc, any advice or help means a lot. Also want to mention all I spend on my cards in total are treated as if they were my debit, I never ever spend more than what I have and never owe
