I came up with a couple of things to try, while I was at lunch.
First, I did a quick SSLLabs scan on the server. That told me that
"sslEnabledProtocols" in an SSLHostConfig was indeed wrong. And it told
me that all simulated Chrome handshakes failed, but most other simulated
handshakes were fine.
Then (directly violating the "change only one variable at a time"
principle) I set it back to "protocols," *and* cut out the cipher list
entirely.
That worked just fine.
The weird part is that so far as I can tell, the cipher list looks
*exactly* like the cipher list in the original Java Keystore version of
the connector
I compared the cipher lists given in the SSLLabs reports for three
cases: the new connector with the old cipher list, the new connector
with no cipher list at all, and (using the live version of the server)
the old connector with the old cipher list, and the results were remarkable:

The test with no cipher list produced (I think) five matches with your
"acceptable" list, two of which were also on your "ideal" list.
The test with the old cipher list on the new connector produced only 12
of the 18 on the "no cipher list" test, none of which were on either of
your lists.
And the original connector produced what appears to be a completely
different list in the report, with nothing in common with the other two,
or with your lists, and yet it is TLS 1.2-only, and it seems to get
along just fine with Chrome.
This is very weird. But at least we have the test working. The next step
is to see if we can get the real site working.
