I have been using Sailfish OS since its launch in 2013 and it works fine, even for regular users (if you install it for them).
I have recently installed it on the Xperia 10 II you mention as well use a couple Xperia X devices in the family. Use the Jolla 1 & Jolla C before back when Jolla still manufactured their own devices.
Frankly, before some of the PinePhone distro mature, this is the only really usable Linux distro based independent mobile OS. And it has been available for years, yet people don't seem to be aware of it or seem to ignore it for some reason.
And if you have any questions about Sailfish OS, fire away! :)
