Math fonts in awesome-cv

Question

I'm using the awesome-cv class file (from here) to write a statement, but I'm unhappy with the math fonts. Specifically, I don't like the result of using \mathbb. Also, math operators (even predefined ones like \log) are italicized while I would like them to be as in \mathrm (as shown below).

I tried installing a different font (Palatino) in the fonts directory, but this did not affect the math font at all.

I would even be willing to change the font entirely using, e.g., \usepackage{mathpazo}, but it doesn't seem to change anything, probably due to specifications in the awesome-cv.cls file.

The awesome-cv.cls file includes the line \RequirePackage[math-style=TeX,vargreek-shape=unicode]{unicode-math}, and it turned out that configuring the math font with this package was most of my problem. Some useful posts: Changing the operator font with unicode-math loaded, Unicode-math changes font outside of range, lost symbols with unicode-math

Final update thanks to Davislor's comments.

MWE:

Thanks for any help!

To turn my comments into an answer: you should seriously consider whether you want to write your paper in a non-standard CV class. However, if you really do, here is what I got to work.

Note that I needed to make several changes to your .cls file to get it to compile at all in TeX Live 2018. I had to change a \newfontfamily to \setfontfamily for a family that had previously been defined in a package it loaded. (A recent version of fontspec made this compatibility-breaking change.) I also had it use the more recent version of the fonts installed on my system. The sourcesanspro package also needed [sfdefault]. That having been done, the problem with the operator names was that the class file loaded unicode-math before you load amsmath. Adding \RequirePackage{amsmath} before \documentclass enabled some hackish workarounds.

ETA: Went back and tweaked it a bit more. Now resizing delimiters and \nabla work.

That image is an unusual mashup of several different fonts. I loaded the math symbols that work correctly from Source Sans Pro, then took the variant Greek letters that are not present from GFS Neohellenic, then fell back to STIX Two Math for the remaining symbols. (You might want the upright math symbols to be different from the body text.)

You shouldn’t load amsfonts or amssymb with unicode-math, as they use legacy font encodings and there are OpenType replacements. You also should use the \setoperatorfont command from unicode-math instead of attempting to redefine operator@font.

There is at least one limitation I left in rather than making the font selection even more overcomplicated. You would need to load yet another math font with [range={\partial,\mitpartial,\mbfpartial,\mbfitpartial}] if for some reason you need to use the upright, italic, bold and bold italic forms of the partial derivative symbol in the same document.
