A lot of people started here with an entry level DSLR. A lot of hobbyists even stay with them. You will get advice from professionals on the internet who tell you what's best for them, but in the end it's what works for you. This is just a suggestion based on your parameters.
It doesn't matter if it's better, it's not OP asked for. OP asked for a beginner camera for under $600 with accessories. The Rebel T7 is beginner camera for $600 with 2 lenses. The Canon EOS R50 is $700 without a lens which would add another $200 or so.
Oh I'm the OP 😅 in where I live it seems that R50 is within my budget (I just pray to god these are not fake cameras somehow as Asia is obsessed with faking products). What do you think about it? Anything to consider?
I'm also considering getting it soon but not sure if Canon 6D (or some Sony camera) would be better. Is that better overall? Currently relying on advice from friendly strangers and some ChatGPT for research.
Oh, my bad. Sorry. Here's the main differences in the link below. Mirrorless is probably more forward thinking, if you can get it for a good price. It has a electronic viewfinder as opposed to an optical one using mirrors in the T7. It will take better pictures in the dark.
