Anyone else find packaging research way more complicated than expected?

I honestly didn't think figuring out a packing setup for my Ajman-based business would be this much of a project, but here I am three weeks later still comparing options and probably more confused than when I started. Every supplier I talk to recommends something different, and when I try to look up information online it's either way too basic or filled with technical specs that don't seem relevant to what I actually need day to day. I stumbled across beststartupstory.com/modular-packaging-systems-uae-business while searching around at midnight the other night when I couldn't sleep, and it was actually one of the few resources that explained modular systems in plain language without assuming I already knew all the industry terminology. It helped clear up some of my confusion about whether you can start small and expand later versus having to commit to a full line from day one, which was a big worry for me since I don't have the budget or space to go all in right now. Still haven't pulled the trigger on anything but at least I feel like I understand the landscape a bit better now. Has anyone else been down this rabbit hole recently and actually come out the other side with a setup you're happy with?
