What is the difference between Eloping vs micro wedding???

I'm trying to figure out what the heck my fiancé and I want to do. He is in the camp of "I could marry you by a river in a van and be happy". He just wants me to be happy. I'm trying to figure out if we do an elopement, micro wedding, or traditional wedding.

The things that are important to me are
our best friend officiating
getting to wear a pretty dress
Close family and friends being there

I just don't know what to do. I'm torn since my fiancé and I don't like loud noise and so having a huge wedding with a DJ doesn't fit us. I also never really dreamed of a "huge dream wedding". I think it would be fun but the stress and expenses are hard to swallow. I've heard of micro weddings as maybe an idea. I originally wanted to just rent a place big enough for 14 of us. Have our friend marry us and spend the weekend hanging out. However because our friend is handicap that makes it really hard to find a place.

We're also thinking maybe elope and have a party a year or so later? But unsure how to do that or how it will work as well? I'm also just so confused what eloping even means anymore....
