Thank you for sharing the British Solo Dance technical requirement document. I find it fascinating! I’m comparing the British rules to what are in the newly revised US Solo dance handbook for 2023. Some terms are different, but I think all the elements in the Rhythm Dance and Free Dance appear to be the same (I’m only looking at the junior & senior requirements). The free dance program duration for seniors appear different for the two countries.I have no idea what the ISU is planning or how solo dance is practiced in other countries besides the US -- although I did hear about it in Britain around the turn of the century before it really took off in the US.
Here's the results page from this year's British Solo Ice Dance Championships:
It looks like they do separate the events by gender. I'm not finding the rules.
Here is the results page from the recent US National Solo Dance Finals:
No separation by gender. Few male skaters participating, but those that do compete in the same events as the girls/women.2022 National Solo Dance Finals

The 2022 USFS rules are available on the Members Only site and are quite extensive, applying to pattern dance, variation dance, and free dance at lower levels, rhythm dance and free dance at higher levels, as well as shadow dance (two skaters performing the same steps of a pattern dance, not touching) at all levels. 2023 rules have not been published yet.
For pattern dances, "The required steps for solo dance will be the same for all competitors. Depending on the dance, the women’s, man’s or a combination of both may be used. Refer to the Pattern Dance Diagrams for the Solo Dance Steps to be skated for each dance."
Free dance elements are similar to those in partnered dance, with Edge Elements instead of lifts.
Illegal elements include jumps of more than one-half revolution, as well as some restrictions on half-revolution jumps.
Whenever the ISU does start an international circuit and publish solo dance rules, undoubtedly the US will follow the international rules for junior and senior levels, which may or may not be significantly different from what they have recently been domestically.
