How do I build a basic financial model for my D2C brand from scratch?

Start with one connected sheet: traffic → conversion → AOV → revenue on top, COGS/shipping/payment/RTO/ad-spend underneath, rolling up to a monthly cash position. Don't buy a tool before you've built this by hand once - the discipline of filling every cell is where you discover the costs you'd been ignoring. Free templates get you 80% of the way; the last 20% is your own SKU-level, channel-level detail.
