Which accessories would be a priority when starting out in the industry?

Good morning!

I currently have a Canon R50 and kit lenses (rfs 18-45mm f 4.5-6.3), a relatively spacious desk, an empty room with excellent natural lighting and two table lamps that I improvised with parchment paper.

I do this just as a hobby, but I already realize the countless limitations I have, mainly because I don't have a tripod and a lens that allows me to zoom in on the details.

Furthermore, I miss more interesting settings that imitate wood or something more rustic. Every day I improvise with something and the cardboards have helped me with that.

Do you have any tips on which items would really be a priority? I see a lot of people talking about the cable to transmit to the computer, but I wouldn't even have anywhere to put this computer and I don't have any subscription to Photoshop, Capture One or anything! I only subscribe to lighroom on my cell phone.

Thanks!
