I have trouble remembering them all, so I decided to make a table of some of the info. I find myself using the architecture on AMD's side, but the generational name on Intel's side. Corrections or updates welcome.

Yeah, I was too lazy to fill in the older Intel mobile CPUs. I think they were near enough same as desktop anyway. Things didn't get complicated until 10th gen.
To the best of my current understanding, AMD have said Zen 3 will be with us this year, but they didn't exactly say in what form. For example, it might be server, not desktop. On that note, I left off server otherwise it gets really confusing. Intel wise I wouldn't expect anything on desktop until next year. Tiger Lake might be an interesting indicator, as it might have Willow Cove and their new Xe graphics.
I have a Ryzen 5 3600 and use the AF 33 eSports. Its excellent imo. Brought temps down from the stock cooler by quite a few degrees - never goes over 60c even under load (unless running a bench but then it goes no higher than 80c) and it's usually around the 40-45c mark for me). Very good for the price i think.
Which tab are you looking at in CPU-Z? Memory or SPD?
If Memory and it shows 1800 Mhz or very close to, then this means they are running at 3600 Mhz as its DDR (Double Data Rate)
