It would be best to try and explore other websites too before settling with one. But to start off, it would be better to look into what you want in your website.
Do you want a search feature on your website? Then you'll have to go with Pro or Business.
Do you plan on selling a lot of items through your weebly website? Then Business is the one you would want to take.
Do you want a domain instead of a sub-domain? (Sub-domains are like rulersky2.brainly.com compared to a domain rulersky2.com.) If you want a domain, then you could even start off with Starter Plan and go all the way up to a Business plan.
But before you chose any plan, compare the plans. See what you need, and what you don't need. And check out which plan has what you need, and get that.
