If I were starting out on this hobby all over again today, I would Get the CSR, CSP, CIP for the big UR bonuses. The points are variable so I can use them in a number of different ways and across the 3 air alliances. I'd product change the CSP to a Freedom after a year and keep the CSR. If your spending patterns in dining and travel aren't more than $3200/year then you PC the CSR to a Freedom. I'd PC the CIP to an Ink Cash. I'd pick up a Marriott card for the annual night and keep it. I'd also pick up a United card for the points and keep that for the extra award availability and lounge passes. There's the first 5 cards and PC to other keeper cards. Notice I wouldn't go for a SW card but that is because my focus is international first class flights. For those who do a lot of domestic travel, getting that CP deal is outstanding!
After passing 5/24 with no plans to ever be under 5/24 again, then I'd see about getting the airline card that would be most valuable to my flight goals. For me that is AA since I am in south FL and Miami is an AA hub. I have both the Barclay and Citi AA cards and keep both. One offers me as pending bonus every year that far outweighs the fee in value. The other, I've had too long to consider cancelling. I'd also pick up and keep an SPG card which is where I put most non bonus category spend. SPG points transfer to over 30 airlines. Plus, for every 20k points you transfer SPG gives you an additional 5k bonus points. That saved me over 50,000 points on the suites flights we just booked. SPG is in a merger with Marriott so we don't really know what will happen with the card next year. This a reason that I was ok with blowing huge amount of SPG points to get the Suite class flights.
I'd consider IHG for your hotel points since you get an annual night at any IHG property upon card anniversary. A night at the Intercontinental in Times Square plus another night using points is not bad for a $49 annual fee. This is another of my keeper cards. My main hotel go to card is Club Carlson for International stays. That card has brought us thousands of dollars in hotel stays for $75 annual fee.
I'd suggest waiting for a really great bonus to pick up any Amex MR earning cards due to their one per lifetime language. Hope this all helps.
