Should I do Big 4 Audit?

Hello

I completed a placement year in Audit within the Big 4. Although I didn't dislike the job, I did find it a bit boring and doing exams alongside work was a slog. I passed 7 exams, so have 8 more to complete (will take approximately 1 year if I pass them all first time) before becoming ACA qualified. I didn't study a relevant degree at university so although I am aware of "exit opportunities" within other areas of finance, I'm not sure which of these I would be best suited to.

I also have a grad job offer on the generalist civil service fast stream. Although I think this job sounds much more interesting, a lot of the reviews on glassdoor say this job doesn't really provide employees with many marketable skills. This is a concern for me in terms of career progression when I know Big 4/ ACA in general is highly regarded. So it makes throwing that away a difficult decision.

My questions are:
1) would the ACA qualification be useful for any other jobs outside of the usual working in industry/ corporate finance/ consultancy?
2) Do you think it is worth me going back to complete the ACA qualification now I've completed a fair few exams?
