I think that you just need to provide .tar of your app. Everything else should be problem for people who handle packages of different distros. You don't wanna be involved in that part of distribution. If people want your app, someone will make a package. There are too many package manages for you to run and add your stuff to all of them. Just have .tar on static http server and that's it!
Example: http://ftp.klid.dk/ftp/gnu/gcc/

Your users on these platforms that you don't seem to understand, aren't expecting _you_ to package your own software, they want the maintainers of their distribution to package it, as they know the distribution, which you probably don't.
Large part of the point of using distributions like Debian and Ubuntu is exactly this, that there are people deeply familiar and knowledgable about the distribution itself, who package the software and apply any needed patches, or wrangle it into what's the standard for the distribution.
When something isn't packaged for these users but they feel like it's popular/useful enough to be, they'll open a request with their distribution for someone to maintain that, in the distribution itself, so everything is aligned. Even though they're not supposed to, some users will bother you and ask you to package it for them, which isn't correct and shouldn't be like that. They either package it themselves, or ask their distribution to do it for them, as the packaging shouldn't have anything to do with the developer of the software.
Parent post already told you a way to distribute your software to Linux users; assuming your tarballs with prebuilt binaries "just work", as in, it's enough to untar it wherever (/opt?) and create a symlink in $PATH for your executable.
But from your comments, the message I get is that you want to apply to become a maintainer in each and every Linux distribution's package repositories, both mainstream and niche? And apparently also create packages for some alternative package managers too? (e.g. mise, npm, Terra)
