I’m personally a canon shooter myself (C400+R5C), so of course I can warmly recommend joining that ecosystem if you’re serious about the hobby. Do realize that is what you’re doing though, when you get started with one brand it becomes hard to switch, so think about if the brand is a good fit for you overall and not just your first purchase.

Canon is great, very solid and reliable and has remained at the top of the game for a long time, maybe not always the craziest innovators but workhorse cameras. Not the cheapest… Especially some accessories are crazy overpriced, and the new RF glass can also be expensive but there’s also some really good cheap options like the small primes and you can adapt almost anything to RF mount.

Fuji I’m less familiar with but I hear is great too and great fun maybe slightly more for casual use, which sounds bad but actually you should think about this carefully because it also means the experience will be a lot more fun and you’ll have an easier time getting good looking results than with the specialist gear which gives you full control but if you don’t know what to do with it then your results will be poor.

Nikon is coming back big time kind of like canon as well, we’re in the return of the kings in this space with the classic Japanese companies doing pretty good at the moment, overall you’ll get a very similar experience as canon with them just a different flavour.
