My Sony DSC-P200 shows a mark in the same spot in every photo, which suggests the problem may be inside the lens rather than on the outside glass. I’ve already cleaned the parts I can reach, but the mark remains. Is there anything else I can try, or does the lens need to be disassembled and cleaned professionally?

That linked PDF looks thorough, and pretty cool!
If you followed the instructions, and you managed to clean the glass elements accessible to you, the next step is to disassemble the zoom lens assembly and clean the elements inside.
Whether this is possible, or even if it's a good idea, is up to you.
The P200 looks like a nice camera, but it was introduced 6 years ago according to DPreview. Unfortunately many compact point-and-shoots are built for economy, not robustness. You may have to conclude that trying to fix this issue isn't worth it.

If the mark appears in the same place in every image and normal exterior cleaning didn’t fix it, the problem is likely inside the lens assembly. On a compact zoom camera like the Sony DSC-P200, that usually means internal dust, a smudge, or possibly fungus caused by moisture and humidity.
At that point, the only real fix is to disassemble the zoom lens and clean the internal elements. That’s delicate work on a compact camera and may not be practical unless you’re very confident with camera repair. Professional cleaning may be possible, but with an older point-and-shoot it may cost more than the camera is worth.
So your realistic options are:
- disassemble the lens and clean internal elements yourself, if you’re comfortable with the risk
- have a repair shop evaluate it
- replace the camera if repair isn’t economical
To help prevent fungus or condensation in the future, store the camera in a dry place with desiccant.
