Are there any adjustable settings when converting from raw to jpg, or is everything baked into the cake?

On-camera or on-computer, it depends.
My D610 has 2 settings for Jpeg:
1. JPEG compression, with 2 selectable choices; Size priority & optimal quality.
2. JPEG quality, which are: Jpeg Basic, Jpeg normal & Jpeg fine.
All the other settings in the Nikon are not JPG settings. They are user prefference settings. Adjustments applied Pre-JPEG conversion, no different from the sliders in ACR or lightroom etc.
The issue with those settings, is that they can be limited in selectable scale, generally has no instant feedback unless someone shoot then chimp, and may require extra reading & understanding skills (not user friendly), aside from being all over the place, sometimes burried under a host of layers in the menu.
In Photoshop, if the open file allows access to the "save as JPEG" menu, the compression called "quality" can be chosen from a scale preset of; Low, Medium, High, Maximum or a 13 step slider that sets the quality from 0 to 12. Higher number provide better quality and bigger file size.
JPEG in Photoshop can also be saved using 2 other ways. With the "save for web" or with the "export as"command.
Each one has their own input method and scale of designating the quality(compression) and some additional adjustments such as resize(Total number of pixels), canvas size (Physical size. A wrong setting here can crop your image or put borders around it) & blur.
Some version of photoshop may allow you to save in JPEG 2000. This is a newer & better jpeg file.
From "save as JPEG 2000", your choices would be:
1. Lossless compression
2. Enter the file size you want (software will choose a quality setting that will compress to target files size)
3. Enter quality using any number from 0 to 100 (Higher the number give better the quality & bigger the file size)
When a shooter use RAW, those preference settings are saved. When an editing software opens the RAW, those settings can be read, interpreted and applied to the RAW file before it appears in the monitor.
If the user makes adjustments and saves the file, those parts affected in the preferences is over written. Hence, a RAW file can be infinitely adjusted and produce many variations, but the RAW data do not change. Only the preference settings are changed, which produce new image interpretations of the RAW file. In imaging parlance, this is called nondestructive edits.
Converting/saving into JPEG produce a new filetype that has discarded much of the RAW & preference data. Its not baked in, its gone. Having done so, JPEG files are less forgiving when it comes to editing them again.
