As of the current moment, it is not possible to configure Musescore 2.3 to output notation that matches the house style of the majority of this site's Finale-based sheets. The number one reason for this is that Musescore does not support 3rd party
music fonts (Maestro, Maestro Wide, EngraverFontSet, etc.) outside its own presets.
So, until Musescore can support 3rd party
music fonts, it is impossible to create Musescore submissions that match Finale's default output.
Here's what needs to happen in the music notation software industry before NSM can integrate Musescore:
(1) Musescore must natively allow 3rd party music fonts, and do so in a way that allows seamless*
(see below) swapping of SMUFL fonts
(2) Makemusic must create an SMUFL-compatible version of Maestro, and then ship this in a future version of Finale Notepad.
*While Finale and Sibelius do allow music font swaps, the fonts themselves have to be optimized for those specific programs. Yes, you can port in SMUFL Bravura to Finale, but it will result in many glyphs not being where they should. This is why things like Fravura/Aruvarb/Norfolk exist (derivatives of Bravura), because no commercial notation software can swap SMUFL fonts seamlessly (except Dorico) without serious typographical anomalies
