I found a Java SMP called MoonySMP that is on season 7 and it is for players who are 16 and up.
It is mostly vanilla but it has some QOL and gameplay plugins so it feels smoother while still being survival.
They want people to join blind and explore to see what the world has.
They also say they have moderation plugins plus a responsive admin team and some premium packs.
A new world is starting tomorrow at 12 PM PST and the seasons stay up as long as the world is active.
