You vaccinate yourself to protect yourself. People who are vaccinated for a disease can and do spread said disease. It's this way for literally everything. The claims that you cannot spread COVID if you're vaccinated were simply false. Vaccination can have a mitigating effect of course, but we were never going to be able to eliminate COVID with something like herd immunity.
The only virus completely eliminated by vaccines is small pox, and that was largely because of a number of ideal factors. The top two are probably that that no animals carried smallpox, only humans. And the second is that infection or vaccination provided lifetime immunity of effectively 100%. This dramatically reduced its potential for mutation and meant that getting rid of it in humans would get rid of it - period.
Coronaviruses, by contrast, are transmissible between humans and animals. This means even if you fully eliminated it in humans, it could, and probably would, come back. This is why flus are basically impossible to get rid of. If you believe CDC numbers then US flu deaths in 2020 were essentially 0, yet now it's back like nothing ever happened. Even the Spanish Flu is still with us as a variant of the common flu. But fortunately most viruses trend towards less lethal mutations over time. Probably natural selection in play - killing your host is not a great path to survival and reproduction.
As for long COVID. I'd rather defer that conversation for a few years. Research on exactly what it is and exactly what causes it is ongoing, and so debating it at this point is just going to be speculation.
But it's quite trivial to see that vaccination will heavily decrease the possibility of transmission - it's like continuously coughing up millions upon millions of viruses vs only re-transmitting a few.
And you are right that in the long term Covid will probably become just like the regular flu, as it mutates to more infectious, but less and less dangerous - but I don't see how it's relevant. At the height of the pandemic not the weakened strains were at play, and you surely know that a^n will either very quickly die out, or very quickly explode depending on the given 'a' - masks, vaccination, and staying home absolutely helped decreasing the possible reach of the disease.
