It isn't hard to upgrade to the latest version of Ubuntu every six months, or to uninstall the non-flatpak version to keep only the flatpak version, or at least test the nightly flatpak temporarily.
As for LTSes: gratis LTS distros give the illusion of stability and security. They are neither more stable nor more secure, you just stay stuck with the same bugs longer, while upstream devs don't support old versions. This is why I stopped using LTSes 13 years ago.

From my perspective as an upstream (i.e. actual developer of the software) who provides solid support to anyone running the latest unmodified version, you are entirely correct.
Unless you are an enterprise customer with a paid SLA, free "LTS" #Linux distros do not give you better "support" than the people actually making the software, and they typically do not fix bugs (if they do, it's unsustainable and they can break things… ex: https://en.wikipedia.org/wiki/Random_number_generator_attack#Debian_OpenSSL).
