[question] going for finance phd or software engineering phd in Canada

I'm going to graduate school in Canada. I am choosing from finance phd and software engineering phd.

I think it is much easier to find a job with software engineering. I really don't find any job when I search "finance phd" on indeed. I also feel it is easier to publish papers in software engineering.

From my understanding, the outcome of a finance phd can vary a lot. Maybe the best phd can go to top company with very high salary, while some others can barely find any job with a finance phd. On the other hand, a software engineering phd can provide stable job for many years.

Btw, when I finish either phd, I will be 35+.

Please give me some advice on which route to go.
