Just beware of OFL with a Reserved Font Name, you can't modify them (and building from source counts as modification) and redistribute without renaming them. This is especially a problem for Debian since they like to build everything from source, including fonts.

Licensing fonts is just such a headache that I would never want to deal with it. They are usually based on metrics that are pretty cumbersome to track.

If you want a custom font where no OFL licensed alternative would work I'd rather hire someone to design a new font. I guess that is also the reason so many companies now have their own custom font (e.g. Spotify, Adobe, etc.).
