It sounds like you want a rolling release distribution. Which means the software repository will have versions close to upstream, or the latest versions shortly after they hit. There’s plenty of those.
The best entry level rolling release distribution is, in my opinion, EndeavourOS. It is based on Arch Linux, but provides a fully working desktop out of the box. It grants you a package manager with a rolling release repository.
Next up would be Arch Linux. Similar to above, but it comes with a minimal system and you have to explicitly install most applications that aren’t required to boot and start a terminal-only session, including your desktop environment.
Next up would be either gentoo or nixos. But I feel like the other two will cover your bases so I won’t talk about those unless you want me to.
