Here is what I have so far. If a small size C203 is needed, I could probably shrink the design a little. For myself I will go for something like this.
Please critizise the routing, those of you with more knowledge than I have! Sorry for the few vias... I don't like them!

Move all text silkscreen away from solder pads to avoid dry joints. Personally I don't put components values on a PCB, that is why you have a bom. It also just clutters things up. Also for example having the components numbers under the components like on R 105 etc. makes it a nightmare to fault find, because the component numbers are now obscured. Furthermore, you may as well use the same narrower trackwidth everywhere, there are no excessive currents flowing, the ground planes are important. Many part numbers overlap and you would not be able to identify them. Do those mods and we have another look, see. "Sorry for the few vias" what is there problem with vias, have as many as you need.

Looks fine, now remove the excessive text and pin numbers and obscured part numbers under components.
Stretch the board to 139 or 140 and 61 or 62, just makes it less complicated and add mounting hole centre to centre so I can actual fit it somewhere without having to use the board as template.
I don't quite follow your thoughts...
1 about obscured texts: The last image shows how the board will look like. I don't need gerbers for the other graphic layers.
2 about dimensions: What exactly is complicated? Could you show where the extra hole(s) is supposed to be?
3 what is mitred and scored? (remember I'm a novice here)

Finally, the PCB manufacturer might bitch about the mounting holes not having centre marks and there is no fiducial to tell him how to line it up perfectly.
Nice work so far.

All your jack plugs have numbers on the pads, the program should warn you, this might be on the screen print, I don't know. A mitred board is one with complex shape and has to be machined, while a scored board has grooves in them so they can be snapped from the panels. There is no extra holes needed. A fiducial is the absolute zero marking on the board where all measurement for everything is taken from, also that tells the manufacturer which is bottom or top. Some PCB manufacturers may add these things for you. Okay, I am knit picking a little just to inform you not to belittle you. You have done a fine job as a "novice"
I never had any complaints so far with my PCBs about mounting holes. All neccessary info are in the gerbers and drill file...
Update for part numbers:
Update for part numbers:
Just another word about the fiducial, it is on every layer, silk, top, bottom, drill ident and holes. This is required by the manufacturer and will not be printed. It is on the exact same spot on every layer.
I have never bothered with the text in the Fab-layers, as I don't send those gerber files to the manufacturer.
I was not aware of the fiducial, and appearantly hase worked fine so far... 🙂

Okay, then I guess you have not designed production boards. Only prototyping or small runs. Those are normally drilled by hand and the use your copper etch to centre the drills. If it was a SMD board they would have complained because even the pick and place machines need the fiducial to put the component in the right place and orientation. This layout is fine and it is a nice job, no complaints at all. I say well done. 👍👍👍
Now lets see your project turn into a product and sold on the marketplace. BTW how would your power supply look or are you thinking about using batteries.
I got nostalgic when you mentioned "production boards". Here is one of my sins from 100 years ago when I made some custom boards while working freelance for a few years. A programmable 4 ch synthesizer. No large scale but definitely not hand drilled. This had 6 or 8 layers, don't remember. Manual routing! The synth filled up a 19" rack box with these Euro-boards.
