In my career I was never asked about GPAs, actually I mainly see them discussed here on EF.
In Italy we were comparing our grades often, only to discover that nobody cares because degrees have legal value and any degree is a degree.
In Switzerland I was only asked once about my transcript of records, but no requirement was listed in the job ad. The sectors I have touched are physics, engineering, IT, health industry. Your specific sector (finance) might be different, my example contributes to the "general context".
I was also working during studies, at some point I had to quit because it was becoming incompatible with the thesis work, but I totally not regret having done it. If you find something that has some value to you, please find some time for it
