that solid layer looks overextruded too
What makes you say that?
I can not be 100% sure, look at the image, between every two middle of lines you have spill between them that is higher than the line made by the flat part of the nozzle. See how light reflects on it and how uneven it is. It is not overextruded "a bit" it is overextruded a lot.
The image can lie!! I might be seeing it wrong, the part that look to me as squeeze between the lines could actually be "hollow" and uneven wavy (in the Z) might be the actual line extruded that is not flatten because nozzle was too high so it is actually severely underextruded. From the single picture I can't be 100% sure ... but I would go with overextruded because looking at the single layer of infill lines I see that infill lines look wider than the flat of your nozzle (as they are wavy on the edges) ... whatever it is I think you need to redo your profile from begining
as I said, can't be 100% sure from the images but look e.g. the circled areas this all is issue, either your nozzle is too high or your flow rate is too high or your trying to print line wider than your nozzle can handle or ... whatever it is, I am pretty sure it is far from perfect and IMO before you start solving any other issue you need to solve three main issues
1. first layer must be perfect
2. three wall empty print must be perfect (print cube, 5-10mm high, empty, no top, only 3 perimeters), walls need to be fused so you cannot push a shaving blade between them, but cannot flow one over another.
3. top layer must be perfect (print solid 5mm high 20x20mm cube and solid layer must be perfect - no ridges, no holes, everything need to be perfectly flat and touching
cheap usb microscope is enough to make this test properly but even a decent mobile phone camera will do
only after these 3 are solved you can move forward and check/test everything else
