I am of opinion that a domain sale is only a comp if it is sold to end user (not trade between investor). I randomly checked some sales in the last 2 years and found four sites in active use: unpublished.xyz, humans.xyz (redirect to an active site), monolith.xyz, and obvious.xyz
I personally don’t like .xyz, but if I were a Vulcan, the logical conclusion is to hold for a few years to see how they work out for you.
Regarding LBGT, I switched to Chinese keyboard and typed in “lb” and “gt” and let keyword prediction does its magic. Each produces several phrases that have neutral or positive meaning. I couldn’t find a useful combination, but someone may.
