Hi, Dylan (Figma CEO) here. You can use local fonts in Figma via a local daemon helper, our native app or by adding the font to a shared library on our Org Plan. (Assuming you have an appropriate license for the font.)
We're also hopeful browsers will expose an API for accessing a list of local fonts / font metrics with the user's permission. (It's a fingerprinting issue to expose this info without the user opting in which is why browsers haven't built something like this in past.) This is gaining traction on the Chrome team, which is really exciting! https://bugs.chromium.org/p/chromium/issues/detail?id=535764...
