Help - What should be my main focus when building an SEO resource collection

I run a software development company but very new to the marketing & SEO world. When I started learning SEO I realized it's a noisy industry. Too many resources and marketing agencies promoting their own tools.

Recently, I have decided to build a simple SEO resource website, which is focused on newcomers & startups.

So these are my questions -

1. Anyone else faced a similar problem when exploring SEO, or just me?
2. What should be my main focus on the platform? - User Experience or More Content
3. Any other feedback?

Anyone who wants to collaborate, I would love to have them onboard, Please Inbox.
