I've now tried a third thunderbolt 10gig ethernet adapter, this time made by QNAP. I get basically the same results with all 3 adapters. I've now tried 3 different cat6 or better ethernet cables directly connected to the ONT with 3 different thunderbolt 10 gig ethernet adapters. I have a 10 gig router which I bought but I don't want to open the packaging if I can't achieve 10 gig speeds when connected directly to the ONT.
After talking to Sonic support again today, I was asked to verify that the laptops I'm using actually support > 1 gigabit speed over thunderbolt 3. So since I have more than one 10 gig adapter now, I tried connecting the two MacBook pro laptops I had tested with before together using a 25' cat6a cable from startech.com. Then I used 'iperf3', installed via Homebrew (
https://brew.sh), and got the following results (one laptop ran 'iperf3 -s' in a terminal window, while the other ran the following):
% iperf3 -Z -c 169.254.150.191 -p 5201

I tried this 4 times and got similar results each time. So this seems to indicate that the two adapters I've tried above are capable of 9.40 Gbits/sec transfer speeds over IP on my laptops. The question remains though, why do I see 1 gigabit speeds via my ONT?
