I'm less familiar with this "new WoW64" than the shared wow64 method so I'll try to build on Debian similar to these Fedora builds.
Based on Debian-Ubuntu "Build from Source" instructions it seems to use Shared WoW64: https://gitlab.winehq.org/wine/wine/-/wikis/Debian-Ubuntu#building-from-sour... (last modified 2025-08-19)
The "new WoW64" mode was added for 9.0: https://gitlab.winehq.org/wine/wine/-/releases/wine-9.0#wow64 (last modified 2024-01-16)
Debian doesn't provide much detail regarding their WoW64 builds but it seems to be using Shared WoW64 as well: https://wiki.debian.org/Wine#Installation_on_Debian_Jessie_and_newer (last modified 2025-05-17)
The Fedora link you provided was last updated 2025-04-24: https://gitlab.winehq.org/wine/wine/-/wikis/Fedora
Fedora isn't terribly out of date but Debian is much more recent which I typically use as my guide for how best run Wine in its latest state.
I'll continue trying the "new Wow64" mode.
Maybe someone more familiar with new vs old Wow64 can make better recommendations.
