MazecraftMC is a semi vanilla survival server that keeps the normal Minecraft feel but adds some quality of life stuff.
It is in Season 2 right now and this season runs until June. The world is already made and the economy is active so you can join in and still have time to build and get known before Season 3.
It supports Java and Bedrock crossplay. The community is small and active most of the day and it is also no pay to win.
You will find backpacks plus dungeons and trials. There are player shops and a jobs and economy system. It also uses Squaremap so you can see the world easier.
