Is there a cost efficient test you guys would recommend that allows me to test yearly if not more?

Not that I know of. The tests that you send off are significantly over $100, which some would find cost-efficient.

If you were just looking for safety tests, your county might offer something significantly cheaper. That is usually testing for bacteria and maybe nitrates, but not iron, manganese, sulfate etc.
Your water test looks good. The thing that would affect taste that I saw is iron. That is a moderate amount of iron, and you might see orange staining in your toilet tanks. A water softener could remove your 0.69ppm of iron. Soft water is better to feed to an RO system because hard water is harder on the life of the membrane. I find numbers for that effect, however.
Your test did not test for tannins, but with a pH of 7.79, tannins seem less likely.
So softener, RO with permeate pump, or both all seem like reasonable options to me to give better tasting water. I have an iron+sulfur filter. I drink the output of that (hard but iron gone), and I also drink softened water.
