Hello!

I'm about to host a LAN with a few friends.
Do you guys have recommendations for good maps for 6 players?
Any gamemodes, PvP PvE...

I was not aware people play Minecraft on pre-made maps? At least outside of adventure maps.

Race for the Wool is always fun, recently played through " Hot and Heavy: Race for the Wool" and it was good. Also if you are interested in modded you can play Reign of Nether the RTS mod. I recently hosted a LAN and we had two players play in the RTS mode and the rest of us just played in survival on their teams and gathered resources to give them.
