I am having issues to understand two things about this thread;
First, why do you think someone will create a server exactly as your liking so you could play in it? I mean, with those specs, almost none will want to play so you are left alone. Just search for relevant specs and try to adapt, I know Its hard but that's life & it keeps on changing, so if your classic-vanilla is no more out there, find something close.
Second, you seem like you are talking alone. All these words you have written for what? You could've created two or three scripts instead.
Finally, game owners & developers don't usually look for a single player to invite to their game, but they go to populated areas and advertise to attract as much as they can. But to get you out of your misery I am going to drop that discord link here. If you felt like pressing, maybe then you can find something similar, I am not sure, but maybe.
Psst, I forgot to mention that the server that I am redirecting you to is still under development 😂😉
