The real benefit for 1K is the ability to change flights without fee, which thus also includes the ability to waitlist.
Book the 1-stop, call and waitlist the non-stop (you should be able to do 2 of them). If it doesn't clear, keep an eye on it within the day or so before flight to see if space opens and call and either reboot or SDC.
