Linux distro to build a binary repo, to maximize compatibility

[Mayuresh <mayuresh%acm.org@localhost>]

I wish to create a binary repository of pkgsrc builds with a goal to
distribute an application <mypkg> to Linux users who may be running
diverse distros.

My installation instructions would have steps:

Option 1: Build natively. Safer, but would take longer time.

    - bootstrap
    
    - install <mypkg> using pkgsrc

Option 2: Use pre-built packages from <myrepo> to save time.

    - bootstrap
    
    - Install pkgin (and deps) using pkg_add from <myrepo>
    
    - PKG_REPOS=<myrepo> pkgin install <mypkg>


I don't expect this to be perfect, given the diversity of the distros,
with libc version compatibility etc.

But I just want to maximize the chances of compatibility with commonly
used distros such as Ubuntu, Debian CentOS etc. of last 3-4 years till
their current versions.

With that goal which distro is advisable to build the binary repo on?

( chatgpt suggested Debian 10 or Ubuntu 18.04 when asked this. )
