I basically also fly solo. I worked for a few years for a company with an excellent track record on things like diversity and I would go home to my sons sometimes and say "If this is excellent, good thing I don't work someplace average because I would be postal already." If BigCo with all the awards for awesomeness is as good as it gets, the only response I can come up with is "Fuck this noise. NO."

To be fair, I was usually saying this about some issue other than being a woman with a job. But I did decide I had no future there and could blithely move on after a senior programmer in the department I wanted a job in asked me for a date. He was the only guy at the entire company in five years of working there who even knew what GIS was without me explaining it and he did not go "OMG. You have a Certificate in GIS? My department could use your skillz!" Or even "Gee, I wonder if she is networking with me and hoping to further her career." Nope, he went straight to "OMG It's a girl and she is interested in some of the same things as me. I wonder if I can get a date!"

"other labels (minority within minority within minority..."

Your description has me curious and sympathetic. What is a "minority within a minority within a minority" in your case?
