I can not see any pixelation. Scaling up x8 does introduce a certain fuzzyness. You can change the interpolation to LoHalo (default is Cubic) but I do not think that will make much difference.
Compression artefacts ? I can not see any of those either, try changing your format to other than jpeg.
You could try the gmic plugin http://www.gmic.eu It does contain upscaling filters, although mostly x2 There is one Upscale (diffusion) in the repair section. Sharper than a regular x8 upscale but you might not like the 'effect'
Otherwise, I do not know. There are oneline "smart / AI" but most seem to charge.
Keep looking-in, someone will have better suggestions.
edit: Just a note about exporting jpegs. The relationship between file size and quality is not linear, There is very little difference in quality between 95 and 100 but the file size will be much smaller. jpeg 100 is not lossless. You could try exporting as a webp format.
