Try turning off ‘Use Wikilinks’ in Settings → Files and links. For me, this autocompletes to [name of link](path/to/file.md) when I start with [[ and some text. (You can configure relative/absolute/etc there as well)
Also, the great plugin ‘Paste URL into selection’ allows me to highlight text I want to turn into a link, then paste in a link from my clipboard. Since ‘Use wikilinks’ is off, it produces a standard markdown link like above as well.
These two together have really made my linking easier, and more cross-platform accessible.
