Two related comments.

First, you might try Fedora Rawhide.  Rawhide is the next version of Fedora
to be released (it is a lot like Debian Sid).  But Fedora releases every 6
months (unlike Debian, which takes a couple of years to release).  With
Fedora, you mostly have the latest version of programs, like GCC.  Rawhide
provides GCC 16.0.1 out of the box.  See <
https://packages.fedoraproject.org/pkgs/gcc/gcc/>.

Second, if you are a free and open source developer, then you can get an
account on the Compile Farm.  The CFarm provides lots of machines with
various compilers.  You will be able to find lots of versions of GCC on the
farm.  See <https://portal.cfarm.net/> and <
https://gcc.gnu.org/wiki/CompileFarm>.  And here is a list of machines and
architectures: <https://portal.cfarm.net/machines/list/>.
