go check out tfcmaps.net
it's a big archive of over 2500 maps that I haven't seen anyone really talk about outside of one steam thread by the archivist behind the website, Arcturus, kinda just wanted to show a bit of what it's got.
here are screenshots of some pretty cool maps made by Bryan "Zouave" Dillow
not all maps are winners, I picked out these maps because I had already explored osaka_r2 and wanted to see more of Zouave's repertoire, most of the maps on the website are pretty basic but sometimes that's all you need to make a fun time.
I do find it cool how Arcturus is still finding maps to update the website with, the most recent update being 3 days ago with 432 unique maps.
