Another thing I should bring up is capital budgeting, which involves financial modeling to see whether a project or capital expenditure is worth undertaking. At my company, this is a broad function that falls under the general corporate finance department, and I believe some of it is done by the business development group. You will be calculating NPV's, IRR's, and all that good stuff, which I'm guessing is the kind of modeling you're talking about. A CFA is good to have for these, but it also probably depends on how heavy the modeling is (i.e., does it require the skills of an investment banker, or are general skills sufficient?) and how often the company needs this type of work done (e.g., daily analysis or on an ad-hoc project basis).

While it would be cool to have a job that explores them all, in reality I don't know of too many jobs where you can wear multiple hats like that, especially larger companies, where the functional departments usually have a fine line of who does what. It might be different for different people, but I was using my company as a model, so I hope it gives you a good idea about what to expect.
