TakeMC Network offers a mix of game modes if you want something a little different. Right now you can jump into ElytraPvP Box, a semi vanilla SMP, and R.E.P.O., which is inspired by the original Steam game. More servers are planned for the future too, so the network looks like it is only going to keep growing.
The server supports both Java and Bedrock crossplay, so it is easy to join no matter which version you play on. If you are looking for a network with PvP, survival, and some unique extra modes in one place, TakeMC is worth checking out.
