Logic Pro has a score editor, along with the other features you listed, and imo is good (subjective) but I’m not sure what is inexpensive to you.

Yeah a couple hundred USD is ok. Logic was high on my list to try, I used it a bit close to 10 years ago 😂
Minus the score editor, I would’ve said LMMS - which is FOSS - but it has limitations. Might still be useful in conjunction with Logic. A lot of good open source synths in that one.
