First, here is the change in ping latency between my machine and cox's first upstream gateway
Checking smokeping now it seems they've changed my gateway IP so my recent data is missing.
I do, however, have about a years worth of speednet download data (4 times a day)
Raw CSV data attached for your perusal. Also I've realized that I don't have my speedtest script locked to a specific server so it may autodetect a different server sometimes. I think that explains the dramatic change in upload speed. As you have already mentioned, not all internet sites have Gb network connections. I am pretty sure I am maxing out the speedtest hosts rather than my internet. I have Google Wifi bandwidth tests that consistently show 700 Mbps down 800 Mbps up. Gaps are from when the machine running the tests was off. You can see I switch to gigablast in Late June 2017. Prior to that I had "300 Mbps" from cox. I think there's a month or so of Centurylink at the beginning.
Also don't forget if you upgrade, you may want faster LAN/wireless, though Cox gave me an 802.11AC router.
