Everyone's going to rant about Arcane Dimensions (and rightly so) but there are other mods.

Alkaline (techbase stuff)
Dwell
Brutalist Jam 1+2
Sprawl 96
Re:Mobilize
Bonk Jam
Christmas + Halloween Jams
Epochs of Enmity
Mjolnir

Plus a bunch of others I can't remember, there's loads. Go looking for one of those grog youtubers who knows the game inside and out, they usually have a good selection of maps to try out.
