Beginner investor with ₱300k: Coop, TDs, or ETFs? (Need advice)

I’m very new to investing and I currently have around ₱300,000 na nasa bank lang. Since I’m still learning and conservative pa ako when it comes to risk, I’m considering putting most of it into safer options like TDs or cooperatives (e.g., OIC, FICCO, Tagum Cooperative).

Mas okay ba na i-split ko yung pera between 2–3 cooperatives for diversification, or okay lang ba ilagay lahat sa isang cooperative? Or would it make more sense na mag-allocate din ako ng portion into ETFs or stocks kahit beginner pa lang ako?

Main goal ko is capital preservation while still earning a decent return. For those with experience, paano niyo personally i-aallocate yung ₱300k in this situation?
