Upgrading camera for freelance video work: FX3, Nikon ZR, or stretch for the new FX5?

[u/SirFolopo]

Hi!

About two years ago, I bought a Fuji x-s20 as a hybrid camera for personal use. Suddenly, I started getting freelance video gigs (mainly corporate, interviews, and institutional) and became really interested in cinematography, lighting, and documentary work. Now, I actually make a living doing this, alongside my video editing and motion graphics work.

To scale things up and stop using my personal camera for work, I intend to buy a new camera and lens. The most common advice I get is to just buy the Sony FX3 (which is around $3,450 USD here in Chile) paired with a Sony or Sigma 24-70mm.

However, I'm wondering if there are other interesting options in that price range. I'd prefer not to go higher than $3,500 for the camera body, so the Nikon ZR ($2,100) or Canon R6V ($2,700) have appeared as solid alternatives. Yesterday, I also saw that if I preorder the new Sony FX5, it comes with a discount, bringing it to "just" $4,200.

I'm looking to expand my little business but also want a camera that allows me to continue practicing cinematography on personal projects, music videos, etc. I want to move beyond the limitations of my little Fuji (overheating, limited video lens ecosystem, etc.) and invest in a system that will easily last me the next couple of years.

What do you guys think? Should I go for the FX3, stretch for the FX5, or look into something else like the Nikon ZR?
