Aviator connectors and any other viable connectors

Aviator connectors
The 5 connectors I know of are:

• GX16
• GX12
• YC8
• XLR-Mini
• LEMO style (extremely expensive)

My question is: What other types of connectors are there (that could be feasibly used as connectors)
I had a look around at different connectors but the aerospace industry doesn't particularly like to say what connectors there are and certainly doesn't have easy access for purchase.

I found GX20 and GX30 and really liked the look of the GX30 connector but it is massive i'm pretty sure (however you can get in 4 pin style so it would be pretty funny to see this on a cable, please message me if someone does it), so that's a little annoying but i also found lots of other connectors mainly on peigenesis but none of them had the same style as the LEMO connectors, I particularly like the look of the LEMO M connector but have no clue as to the diameter. If anyone knows of any other viable connectors that would be great.

I am extremely new to geekhack and so my formatting is garbage (pls don't bully me)

Ok after looking at RS components for a while I have discovered that I am massively out of my depth and this is far more complex than I thought, things like A, B and C type connectors and many other technical specifications I have no clue on how it works. if anyone could translate this into baby speak so I can understand it that would be useful.
