According to this page: https://github.com/dbenjaminmiller/bmusicfonts/tree/master
you can use something called esmuflily and ekmelily so that any smufl font can be used in Lilypond. I have not personally tried this so i can't comment on how it works. I am not aware of what work is currently being done to add official smufl support to Lilypond. Abraham's fonts still work though they are now unmaintained. There were the old versions (pre-MTF versions) and the ones available through MTF, they probably have most of the glyphs you'll need in common music notation. I've played around with the old free ones, they still work fine. If you're interested in Bravura specifically, it's probably easiest to just use BMusicFont instead. Gonville is another font option, it seems to be still maintained. Another possibility you should be aware of: it's easy to swap out portions of the music font for other fonts if there's something particular from those fonts that you like. Like clefs, accidentals, flags, articulations, noteheads, etc. Like Cadence clefs, Beethoven noteheads, Gonville sharps and flats... That's all I know about that, hope that helps
