Advice on joining Chase cards

Ok, so I plan on getting both the Chase Sapphire Preferred and the Chase Freedom Flex cards eventually. I just realized I missed the CSP 100k sign up bonus and now it is at 60k. Should I just get the CFF now, and wait until the CSP has a higher bonus offer? Or should I just go ahead and get both cards?

I don't plan on using using the points anytime soon, but am mainly wondering if it would be worth it to wait for a higher bonus or sign up now. Would the 2% on other travel, and 10% bonus on earned points be worth the potential of a higher bonus and the annual fee?
