In case you should look for other software:
Have a look at Myriad
(from France). Their title PDFtoMusic comes in two editions. Last time I calculated (some 15 years ago), buying the standard edition plus their flagship notator/sequencer Harmony Assistant would be cheaper than buying PDFtoMusic Pro only. All(?) of their software is available for macOS, Windows and Linux. All products are one-time purchases, but their definition of "product" may be more limited than yours. And be prepared for a steep learning curve.
Me, I have had most of their titles for some 15..20 years (Windows, macOS and Linux shorter), but I haven't really used them. (I had been away from music for most of that time.)
