I know in general CYs have a very negative view here on FT. But in general, over the last 10 years, I've had much, much better suite upgrade rates at CYs than I have had with any other non-suite Marriott brand. Just before I check-in, I usually check to see if they are still selling suite rooms. If they are, I will ask about an upgrade to one when I check in. And my upgrade rate is very good, assuming they were still selling them for the nights I'm staying.

Yes, I know generally they don't provide free breakfast but otherwise, I tend to like them. I love their suite room layout as they have two separate thermostats (one for each room.) I can really crank up the A/C for the bedroom as I like to sleep with it cold in the room, but don't like sitting in the room working or watching TV or whatever when it is 60 degree. A CY King Suite is perfect for me. I know a lot of folks say Hilton's HGI brand tends to be better and agree free breakfast there is a great benefit, but I've never, even as a Diamond, been able to get a true suite upgrade. I have been able to get Jr. Suite upgrades which are nice, but not as good as the CY full suite upgrade I usually get.

I do like RIs and even TPSes can be OK, but I hate that 5pts/$ thing. So I'll use points to stay at an RI or TPS, but am much less likely to have a paid stay at one.
